    #   @option options [Array<Seahorse::Client::Plugin>] :plugins ([]])
    #     A list of plugins to apply to the client. Each plugin is either a
    #     class name or an instance of a plugin class.
    #
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials used for authentication. This can be any class that includes and implements
    #     `Aws::CredentialProvider`, or instance of any one of the following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::SharedCredentials` - Used for loading static credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     * `Aws::AssumeRoleWebIdentityCredentials` - Used when you need to
    #       assume a role after providing credentials via the web.
    #
    #     * `Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an
    #       access token generated from `aws login`.
    #
    #     * `Aws::ProcessCredentials` - Used for loading credentials from a
    #       process that outputs to stdout.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::ECSCredentials` - Used for loading credentials from
    #       instances running in ECS.
    #
    #     * `Aws::CognitoIdentityCredentials` - Used for loading credentials
    #       from the Cognito Identity service.
    #
    #     When `:credentials` are not configured directly, the following locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #
    #     * The `:access_key_id`, `:secret_access_key`, `:session_token`, and
    #       `:account_id` options.
    #
    #     * `ENV['AWS_ACCESS_KEY_ID']`, `ENV['AWS_SECRET_ACCESS_KEY']`,

    #     * `~/.aws/credentials`
    #
    #     * `~/.aws/config`
    #
    #     * EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive.
    #       Construct and pass an instance of `Aws::InstanceProfileCredentials` or `Aws::ECSCredentials` to
    #       enable retries and extended timeouts. Instance profile credential fetching can be disabled by

    #
    #   @option options [Boolean] :adaptive_retry_wait_to_fill (true)
    #     Used only in `adaptive` retry mode.  When true, the request will sleep
    #     until there is sufficent client side capacity to retry the request.
    #     When false, the request will raise a `RetryCapacityNotAvailableError` and will
    #     not retry instead of sleeping.
    #
    #   @option options [Array<String>] :auth_scheme_preference
    #     A list of preferred authentication schemes to use when making a request. Supported values are:

    #     shared config as `auth_scheme_preference`, the value should be a comma-separated list.
    #
    #   @option options [Boolean] :client_side_monitoring (false)
    #     When `true`, client-side metrics will be collected for all API requests from
    #     this client.
    #
    #   @option options [String] :client_side_monitoring_client_id ("")
    #     Allows you to provide an identifier for this client which will be attached to

    #     4 times. Used in `standard` and `adaptive` retry modes.
    #
    #   @option options [String] :profile ("default")
    #     Used when loading credentials from the shared credentials file at `HOME/.aws/credentials`.
    #     When not specified, 'default' is used.
    #
    #   @option options [String] :request_checksum_calculation ("when_supported")
    #     Determines when a checksum will be calculated for request payloads. Values are:
    #
    #     * `when_supported` - (default) When set, a checksum will be
    #       calculated for all request payloads of operations modeled with the
    #       `httpChecksum` trait where `requestChecksumRequired` is `true` and/or a
    #       `requestAlgorithmMember` is modeled.

    #
    #   @option options [Integer] :retry_limit (3)
    #     The maximum number of times to retry failed requests.  Only
    #     ~ 500 level server errors and certain ~ 400 level client errors
    #     are retried.  Generally, these are throttling errors, data
    #     checksum errors, networking errors, timeout errors, auth errors,
    #     endpoint discovery, and errors from expired credentials.
    #     This option is only used in the `legacy` retry mode.
    #
    #   @option options [Integer] :retry_max_delay (0)
    #     The maximum number of seconds to delay between retries (0 for no limit)
    #     used by the default backoff function. This option is only used in the

    #
    #     * `adaptive` - An experimental retry mode that includes all the
    #       functionality of `standard` mode along with automatic client side
    #       throttling.  This is a provisional mode that may change behavior
    #       in the future.
    #
    #   @option options [String] :sdk_ua_app_id
    #     A unique and opaque application ID that is appended to the
    #     User-Agent header as app/sdk_ua_app_id. It should have a

    #     * `~/.aws/config`
    #
    #   @option options [Boolean] :stub_responses (false)
    #     Causes the client to return stubbed responses. By default
    #     fake responses are generated and returned. You can specify
    #     the response data to return or errors to raise by calling
    #     {ClientStubs#stub_responses}. See {ClientStubs} for more information.
    #
    #     ** Please note ** When response stubbing is enabled, no HTTP
    #     requests are made, and retries are disabled.

    #     Allows you to provide a telemetry provider, which is used to
    #     emit telemetry data. By default, uses `NoOpTelemetryProvider` which
    #     will not record or emit any telemetry data. The SDK supports the
    #     following telemetry providers:
    #
    #     * OpenTelemetry (OTel) - To use the OTel provider, install and require the
    #     `opentelemetry-sdk` gem and then, pass in an instance of a

    #       tokens.
    #
    #     * `Aws::SSOTokenProvider` - Used for loading tokens from AWS SSO using an
    #       access token generated from `aws login`.
    #
    #     When `:token_provider` is not configured directly, the `Aws::TokenProviderChain`
    #     will be used to search for tokens configured for your profile in shared configuration files.
    #
    #   @option options [Boolean] :use_dualstack_endpoint
    #     When set to `true`, dualstack enabled endpoints (with `.aws` TLD)
    #     will be used if available.
    #
    #   @option options [Boolean] :use_fips_endpoint
    #     When set to `true`, fips compatible endpoints will be used if available.

    #   @option options [Float] :http_continue_timeout (1)
    #     The number of seconds to wait for a 100-continue response before sending the
    #     request body.  This option has no effect unless the request has "Expect"
    #     header set to "100-continue".  Defaults to `nil` which  disables this
    #     behaviour.  This value can safely be set per request on the session.
    #
    #   @option options [Float] :http_idle_timeout (5)
    #     The number of seconds a connection is allowed to sit idle before it
    #     is considered stale.  Stale connections are closed and removed from the
    #     pool before making a request.
    #
    #   @option options [Float] :http_open_timeout (15)
    #     The default number of seconds to wait for response data.

    #     of the response body is received. It provides three arguments: the chunk,
    #     the number of bytes received, and the total number of
    #     bytes in the response (or nil if the server did not send a `content-length`).
    #
    #   @option options [Proc] :on_chunk_sent
    #     When a Proc object is provided, it will be used as callback when each chunk
    #     of the request body is sent. It provides three arguments: the chunk,

    # Continues rolling back a stack from `UPDATE_ROLLBACK_FAILED` to
    # `UPDATE_ROLLBACK_COMPLETE` state. Depending on the cause of the
    # failure, you can manually fix the error and continue the rollback. By
    # continuing the rollback, you can return your stack to a working state
    # (the `UPDATE_ROLLBACK_COMPLETE` state) and then try to update the
    # stack again.
    #
    # A stack enters the `UPDATE_ROLLBACK_FAILED` state when CloudFormation
    # can't roll back all changes after a failed stack update. For example,
    # this might occur when a stack attempts to roll back to an old database
    # that was deleted outside of CloudFormation. Because CloudFormation
    # doesn't know the instance was deleted, it assumes the instance still
    # exists and attempts to roll back to it, causing the update rollback to
    # fail.

    # @option params [required, String] :stack_name
    #   The name or the unique ID of the stack that you want to continue
    #   rolling back.
    #
    #   <note markdown="1"> Don't specify the name of a nested stack (a stack that was created by
    #   using the `AWS::CloudFormation::Stack` resource). Instead, use this

    #
    #    </note>
    #
    # @option params [String] :role_arn
    #   The Amazon Resource Name (ARN) of an IAM role that CloudFormation
    #   assumes to roll back the stack. CloudFormation uses the role's
    #   credentials to make calls on your behalf. CloudFormation always uses
    #   this role for all future operations on the stack. Provided that users
    #   have permission to operate on the stack, CloudFormation uses this role
    #   even if the users don't have permission to pass it. Ensure that the
    #   role grants least permission.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,
    #   CloudFormation uses a temporary session that's generated from your
    #   user credentials.
    #
    # @option params [Array<String>] :resources_to_skip
    #   A list of the logical IDs of the resources that CloudFormation skips
    #   during the continue update rollback operation. You can specify only
    #   resources that are in the `UPDATE_FAILED` state because a rollback
    #   failed. You can't specify resources that are in the `UPDATE_FAILED`
    #   state for other reasons, for example, because an update was canceled.
    #   To check why a resource update failed, use the DescribeStackResources
    #   action, and view the resource status reason.
    #
    #   Specify this property to skip rolling back resources that
    #   CloudFormation can't successfully roll back. We recommend that you [
    #   troubleshoot][1] resources before skipping them. CloudFormation sets
    #   the status of the specified resources to `UPDATE_COMPLETE` and
    #   continues to roll back the stack. After the rollback is complete, the
    #   state of the skipped resources will be inconsistent with the state of
    #   the resources in the stack template. Before performing another stack
    #   update, you must update the stack or resources to be consistent with
    #   each other. If you don't, subsequent stack updates might fail, and
    #   the stack will become unrecoverable.
    #
    #   Specify the minimum number of resources required to successfully roll
    #   back your stack. For example, a failed resource update might cause
    #   dependent resources to fail. In this case, it might not be necessary
    #   to skip the dependent resources.
    #
    #   To skip resources that are part of nested stacks, use the following
    #   format: `NestedStackName.ResourceLogicalID`. If you want to specify
    #   the logical ID of a stack resource (`Type:
    #   AWS::CloudFormation::Stack`) in the `ResourcesToSkip` list, then its
    #   corresponding embedded stack must be in one of the following states:
    #   `DELETE_IN_PROGRESS`, `DELETE_COMPLETE`, or `DELETE_FAILED`.
    #
    #   <note markdown="1"> Don't confuse a child stack's name with its corresponding logical ID
    #   defined in the parent stack. For an example of a continue update
    #   rollback operation with nested stacks, see [Continue rolling back from
    #   failed nested stack updates][2].

    #     Some template contain macros. Macros perform custom processing on
    #     templates; this can include simple actions like find-and-replace
    #     operations, all the way to extensive transformations of entire
    #     templates. Because of this, users typically create a change set from
    #     the processed template, so that they can review the changes
    #     resulting from the macros before actually creating the stack. If
    #     your stack template contains one or more macros, and you choose to
    #     create a stack directly from the processed template, without first
    #     reviewing the resulting changes in a change set, you must
    #     acknowledge this capability. This includes the [AWS::Include][10]
    #     and [AWS::Serverless][11] transforms, which are macros hosted by
    #     CloudFormation.
    #
    #     <note markdown="1"> This capacity doesn't apply to creating change sets, and specifying
    #     it when creating change sets has no effect.
    #
    #      If you want to create a stack from a stack template that contains
    #     macros *and* nested stacks, you must create or update the stack
    #     directly from the template using the CreateStack or UpdateStack
    #     action, and specifying this capability.

    #   you execute this change set, such as `AWS::EC2::Instance`,
    #   `AWS::EC2::*`, or `Custom::MyCustomInstance`.

    #
    # @option params [String] :role_arn
    #   The Amazon Resource Name (ARN) of an IAM role that CloudFormation
    #   assumes when executing the change set. CloudFormation uses the role's
    #   credentials to make calls on your behalf. CloudFormation uses this
    #   role for all future operations on the stack. Provided that users have
    #   permission to operate on the stack, CloudFormation uses this role even
    #   if the users don't have permission to pass it. Ensure that the role
    #   grants least permission.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,
    #   CloudFormation uses a temporary session that is generated from your
    #   user credentials.
    #
    # @option params [Types::RollbackConfiguration] :rollback_configuration
    #   The rollback triggers for CloudFormation to monitor during stack
    #   creation and updating operations, and for the specified monitoring
    #   period afterwards.
    #
    # @option params [Array<String>] :notification_arns
    #   The Amazon Resource Names (ARNs) of Amazon SNS topics that
    #   CloudFormation associates with the stack. To remove all associated
    #   notification topics, specify an empty list.
    #
    # @option params [Array<Types::Tag>] :tags
    #   Key-value pairs to associate with this stack. CloudFormation also
    #   propagates these tags to resources in the stack. You can specify a
    #   maximum of 50 tags.
    #
    # @option params [required, String] :change_set_name
    #   The name of the change set. The name must be unique among all change
    #   sets that are associated with the specified stack.
    #
    #   A change set name can contain only alphanumeric, case sensitive
    #   characters, and hyphens. It must start with an alphabetical character
    #   and can't exceed 128 characters.
    #
    # @option params [String] :client_token
    #   A unique identifier for this `CreateChangeSet` request. Specify this
    #   token if you plan to retry requests so that CloudFormation knows that
    #   you're not attempting to create another change set with the same
    #   name. You might retry `CreateChangeSet` requests to ensure that
    #   CloudFormation successfully received them.
    #
    # @option params [String] :description
    #   A description to help you identify this change set.
    #
    # @option params [String] :change_set_type
    #   The type of change set operation. To create a change set for a new
    #   stack, specify `CREATE`. To create a change set for an existing stack,
    #   specify `UPDATE`. To create a change set for an import operation,
    #   specify `IMPORT`.
    #
    #   If you create a change set for a new stack, CloudFormation creates a
    #   stack with a unique stack ID, but no template or resources. The stack
    #   will be in the `REVIEW_IN_PROGRESS` state until you execute the change
    #   set.
    #
    #   By default, CloudFormation specifies `UPDATE`. You can't use the
    #   `UPDATE` type to create a change set for a new stack or the `CREATE`
    #   type to create a change set for an existing stack.
    #
    # @option params [Array<Types::ResourceToImport>] :resources_to_import
    #   The resources to import into your stack.
    #
    # @option params [Boolean] :include_nested_stacks
    #   Creates a change set for the all nested stacks specified in the
    #   template. The default behavior of this action is set to `False`. To
    #   include nested sets in a change set, specify `True`.
    #
    # @option params [String] :on_stack_failure
    #   Determines what action will be taken if stack creation fails. If this
    #   parameter is specified, the `DisableRollback` parameter to the
    #   [ExecuteChangeSet][1] API operation must not be specified. This must
    #   be one of these values:
    #
    #   * `DELETE` - Deletes the change set if the stack creation fails. This
    #     is only valid when the `ChangeSetType` parameter is set to `CREATE`.
    #     If the deletion of the stack fails, the status of the stack is
    #     `DELETE_FAILED`.
    #
    #   * `DO_NOTHING` - if the stack creation fails, do nothing. This is
    #     equivalent to specifying `true` for the `DisableRollback` parameter
    #     to the [ExecuteChangeSet][1] API operation.
    #
    #   * `ROLLBACK` - if the stack creation fails, roll back the stack. This
    #     is equivalent to specifying `false` for the `DisableRollback`
    #     parameter to the [ExecuteChangeSet][1] API operation.
    #
    #   For nested stacks, when the `OnStackFailure` parameter is set to
    #   `DELETE` for the change set for the parent stack, any failure in a
    #   child stack will cause the parent stack creation to fail and all
    #   stacks to be deleted.

    #   [1]: https://docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_ExecuteChangeSet.html

    #   Indicates if the change set auto-imports resources that already exist.
    #   For more information, see [Import Amazon Web Services resources into a
    #   CloudFormation stack automatically][1] in the *CloudFormation User
    #   Guide*.
    #
    #   <note markdown="1"> This parameter can only import resources that have custom names in
    #   templates. For more information, see [name type][2] in the
    #   *CloudFormation User Guide*. To import resources that do not accept

    #     templates; this can include simple actions like find-and-replace
    #     operations, all the way to extensive transformations of entire
    #     templates. Because of this, users typically create a change set from
    #     the processed template, so that they can review the changes
    #     resulting from the macros before actually creating the stack. If
    #     your stack template contains one or more macros, and you choose to
    #     create a stack directly from the processed template, without first
    #     reviewing the resulting changes in a change set, you must
    #     acknowledge this capability. This includes the [AWS::Include][10]
    #     and [AWS::Serverless][11] transforms, which are macros hosted by
    #     CloudFormation.
    #
    #     If you want to create a stack from a stack template that contains
    #     macros *and* nested stacks, you must create the stack directly from
    #     the template using this capability.
    #
    #     You should only create stacks directly from a stack template that
    #     contains macros if you know what processing the macro performs.
    #
    #      Each macro relies on an underlying Lambda service function for
    #     processing stack templates. Be aware that the Lambda function owner
    #     can update the function operation without CloudFormation being
    #     notified.
    #
    #     For more information, see [Perform custom processing on
    #     CloudFormation templates with template macros][12].

    # @option params [Array<String>] :resource_types
    #   The template resource types that you have permissions to work with for
    #   this create stack action, such as `AWS::EC2::Instance`, `AWS::EC2::*`,
    #   or `Custom::MyCustomInstance`. Use the following syntax to describe
    #   template resource types: `AWS::*` (for all Amazon Web Services
    #   resources), `Custom::*` (for all custom resources),
    #   `Custom::logical_ID ` (for a specific custom resource),
    #   `AWS::service_name::*` (for all resources of a particular Amazon Web
    #   Services service), and `AWS::service_name::resource_logical_ID ` (for
    #   a specific Amazon Web Services resource).
    #
    #   If the list of resource types doesn't include a resource that you're
    #   creating, the stack creation fails. By default, CloudFormation grants
    #   permissions to all resource types. IAM uses this parameter for
    #   CloudFormation-specific condition keys in IAM policies. For more
    #   information, see [Control access with Identity and Access
    #   Management][1].

    #
    # @option params [String] :role_arn
    #   The Amazon Resource Name (ARN) of an IAM role that CloudFormation
    #   assumes to create the stack. CloudFormation uses the role's
    #   credentials to make calls on your behalf. CloudFormation always uses
    #   this role for all future operations on the stack. Provided that users
    #   have permission to operate on the stack, CloudFormation uses this role
    #   even if the users don't have permission to pass it. Ensure that the
    #   role grants least privilege.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,
    #   CloudFormation uses a temporary session that's generated from your
    #   user credentials.
    #
    # @option params [String] :on_failure
    #   Determines what action will be taken if stack creation fails. This
    #   must be one of: `DO_NOTHING`, `ROLLBACK`, or `DELETE`. You can specify
    #   either `OnFailure` or `DisableRollback`, but not both.
    #
    #   <note markdown="1"> Although the default setting is `ROLLBACK`, there is one exception.
    #   This exception occurs when a StackSet attempts to deploy a stack
    #   instance and the stack instance fails to create successfully. In this
    #   case, the `CreateStack` call overrides the default setting and sets
    #   the value of `OnFailure` to `DELETE`.
    #
    #    </note>
    #
    #   Default: `ROLLBACK`
    #
    # @option params [String] :stack_policy_body
    #   Structure that contains the stack policy body. For more information,
    #   see [Prevent updates to stack resources][1] in the *CloudFormation
    #   User Guide*. You can specify either the `StackPolicyBody` or the
    #   `StackPolicyURL` parameter, but not both.
    #
    #
    #
    #   [1]: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/protect-stack-resources.html
    #
    # @option params [String] :stack_policy_url
    #   Location of a file that contains the stack policy. The URL must point
    #   to a policy (maximum size: 16 KB) located in an S3 bucket in the same
    #   Region as the stack. The location for an Amazon S3 bucket must start
    #   with `https://`. URLs from S3 static websites are not supported.
    #
    #   You can specify either the `StackPolicyBody` or the `StackPolicyURL`
    #   parameter, but not both.
    #
    # @option params [Array<Types::Tag>] :tags
    #   Key-value pairs to associate with this stack. CloudFormation also
    #   propagates these tags to the resources created in the stack. A maximum
    #   number of 50 tags can be specified.
    #
    # @option params [String] :client_request_token
    #   A unique identifier for this `CreateStack` request. Specify this token
    #   if you plan to retry requests so that CloudFormation knows that
    #   you're not attempting to create a stack with the same name. You might
    #   retry `CreateStack` requests to ensure that CloudFormation
    #   successfully received them.
    #
    #   All events initiated by a given stack operation are assigned the same
    #   client request token, which you can use to track operations. For
    #   example, if you execute a `CreateStack` operation with the token
    #   `token1`, then all the `StackEvents` generated by that operation will
    #   have `ClientRequestToken` set as `token1`.
    #
    #   In the console, stack operations display the client request token on
    #   the Events tab. Stack operations that are initiated from the console
    #   use the token format *Console-StackOperation-ID*, which helps you
    #   easily identify the stack operation . For example, if you create a
    #   stack using the console, each stack event would be assigned the same
    #   token in the following format:
    #   `Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002`.
    #
    # @option params [Boolean] :enable_termination_protection
    #   Whether to enable termination protection on the specified stack. If a
    #   user attempts to delete a stack with termination protection enabled,
    #   the operation fails and the stack remains unchanged. For more
    #   information, see [Protect CloudFormation stacks from being deleted][1]
    #   in the *CloudFormation User Guide*. Termination protection is
    #   deactivated on stacks by default.
    #
    #   For [nested stacks][2], termination protection is set on the root
    #   stack and can't be changed directly on the nested stack.

    #
    #   Any overridden parameter values will be applied to all stack instances
    #   in the specified accounts and Amazon Web Services Regions. When
    #   specifying parameters and their values, be aware of how CloudFormation
    #   sets parameter values during stack instance operations:
    #
    #   * To override the current value for a parameter, include the parameter
    #     and specify its value.
    #
    #   * To leave an overridden parameter set to its present value, include
    #     the parameter and specify `UsePreviousValue` as `true`. (You can't
    #     specify both a value and set `UsePreviousValue` to `true`.)
    #
    #   * To set an overridden parameter back to the value specified in the
    #     StackSet, specify a parameter list but don't include the parameter
    #     in the list.
    #
    #   * To leave all parameters set to their present values, don't specify
    #     this property at all.
    #
    #   During StackSet updates, any parameter values overridden for a stack
    #   instance aren't updated, but retain their overridden value.
    #
    #   You can only override the parameter *values* that are specified in the

    #   to update the StackSet template.

    # @option params [Types::StackSetOperationPreferences] :operation_preferences
    #   Preferences for how CloudFormation performs this StackSet operation.
    #
    # @option params [String] :operation_id
    #   The unique identifier for this StackSet operation.
    #
    #   The operation ID also functions as an idempotency token, to ensure
    #   that CloudFormation performs the StackSet operation only once, even if
    #   you retry the request multiple times. You might retry StackSet
    #   operation requests to ensure that CloudFormation successfully received
    #   them.
    #
    #   If you don't specify an operation ID, the SDK generates one

    #
    # @option params [String] :template_url
    #   The URL of a file that contains the template body. The URL must point
    #   to a template (maximum size: 1 MB) that's located in an Amazon S3
    #   bucket or a Systems Manager document. The location for an Amazon S3
    #   bucket must start with `https://`. S3 static website URLs are not
    #   supported.

    #
    # @option params [String] :stack_id
    #   The stack ID you are importing into a new StackSet. Specify the Amazon
    #   Resource Name (ARN) of the stack.
    #
    # @option params [Array<Types::Parameter>] :parameters
    #   The input parameters for the StackSet template.
    #
    # @option params [Array<String>] :capabilities
    #   In some cases, you must explicitly acknowledge that your StackSet
    #   template contains certain capabilities in order for CloudFormation to
    #   create the StackSet and related stack instances.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your Amazon Web Services account; for example, by
    #     creating new IAM users. For those StackSets, you must explicitly
    #     acknowledge this by specifying one of these capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, CloudFormation
    #       returns an `InsufficientCapabilities` error.
    #     If your stack template contains these resources, we recommend that
    #     you review all permissions associated with them and edit their
    #     permissions if necessary.
    #
    #     * [AWS::IAM::AccessKey][1]
    #
    #     * [AWS::IAM::Group][2]

    #     * [AWS::IAM::UserToGroupAddition][7]
    #     For more information, see [Acknowledging IAM resources in
    #     CloudFormation templates][8].
    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some templates reference macros. If your StackSet template
    #     references one or more macros, you must create the StackSet directly
    #     from the processed template, without first reviewing the resulting
    #     changes in a change set. To create the StackSet directly, you must
    #     acknowledge this capability. For more information, see [Perform
    #     custom processing on CloudFormation templates with template
    #     macros][9].
    #
    #     StackSets with service-managed permissions don't currently support
    #     the use of macros in templates. (This includes the
    #     [AWS::Include][10] and [AWS::Serverless][11] transforms, which are
    #     macros hosted by CloudFormation.) Even if you specify this
    #     capability for a StackSet with service-managed permissions, if you
    #     reference a macro in your template the StackSet operation will fail.

    #   supported resources that are created in the stacks. A maximum number
    #   of 50 tags can be specified.
    #
    #   If you specify tags as part of a `CreateStackSet` action,
    #   CloudFormation checks to see if you have the required IAM permission
    #   to tag resources. If you don't, the entire `CreateStackSet` action
    #   fails with an `access denied` error, and the StackSet is not created.
    #
    # @option params [String] :administration_role_arn
    #   The Amazon Resource Name (ARN) of the IAM role to use to create this
    #   StackSet.

    # @option params [Array<String>] :retain_resources
    #   For stacks in the `DELETE_FAILED` state, a list of resource logical
    #   IDs that are associated with the resources you want to retain. During
    #   deletion, CloudFormation deletes the stack but doesn't delete the
    #   retained resources.
    #
    #   Retaining resources is useful when you can't delete a resource, such
    #   as a non-empty S3 bucket, but you want to delete the stack.
    #
    # @option params [String] :role_arn
    #   The Amazon Resource Name (ARN) of an IAM role that CloudFormation
    #   assumes to delete the stack. CloudFormation uses the role's
    #   credentials to make calls on your behalf.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,
    #   CloudFormation uses a temporary session that's generated from your
    #   user credentials.
    #
    # @option params [String] :client_request_token
    #   A unique identifier for this `DeleteStack` request. Specify this token
    #   if you plan to retry requests so that CloudFormation knows that
    #   you're not attempting to delete a stack with the same name. You might
    #   retry `DeleteStack` requests to ensure that CloudFormation
    #   successfully received them.
    #
    #   All events initiated by a given stack operation are assigned the same
    #   client request token, which you can use to track operations. For
    #   example, if you execute a `CreateStack` operation with the token
    #   `token1`, then all the `StackEvents` generated by that operation will
    #   have `ClientRequestToken` set as `token1`.
    #
    #   In the console, stack operations display the client request token on
    #   the Events tab. Stack operations that are initiated from the console
    #   use the token format *Console-StackOperation-ID*, which helps you
    #   easily identify the stack operation . For example, if you create a
    #   stack using the console, each stack event would be assigned the same
    #   token in the following format:
    #   `Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002`.

    #   * `STANDARD` - Use the standard behavior. Specifying this value is the
    #     same as not specifying this parameter.
    #
    #   * `FORCE_DELETE_STACK` - Delete the stack if it's stuck in a
    #     `DELETE_FAILED` state due to resource deletion failure.

    #   The unique identifier for this StackSet operation.
    #
    #   If you don't specify an operation ID, the SDK generates one
    #   automatically.
    #
    #   The operation ID also functions as an idempotency token, to ensure
    #   that CloudFormation performs the StackSet operation only once, even if
    #   you retry the request multiple times. You can retry StackSet operation
    #   requests to ensure that CloudFormation successfully received them.
    #
    #   Repeating this StackSet operation with a new operation ID retries all
    #   stack instances whose status is `OUTDATED`.

    #
    # @option params [Array<String>] :capabilities
    #   In some cases, you must explicitly acknowledge that your stack
    #   template contains certain capabilities in order for CloudFormation to
    #   update the stack.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your Amazon Web Services account, for example, by
    #     creating new IAM users. For those stacks, you must explicitly
    #     acknowledge this by specifying one of these capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, CloudFormation
    #       returns an `InsufficientCapabilities` error.
    #     If your stack template contains these resources, we suggest that you
    #     review all permissions associated with them and edit their
    #     permissions if necessary.

    #     * [ AWS::IAM::AccessKey][1]
    #
    #     * [ AWS::IAM::Group][2]

    #     For more information, see [Acknowledging IAM resources in
    #     CloudFormation templates][9].
    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some template contain macros. Macros perform custom processing on
    #     templates; this can include simple actions like find-and-replace
    #     operations, all the way to extensive transformations of entire
    #     templates. Because of this, users typically create a change set from
    #     the processed template, so that they can review the changes
    #     resulting from the macros before actually updating the stack. If
    #     your stack template contains one or more macros, and you choose to
    #     update a stack directly from the processed template, without first
    #     reviewing the resulting changes in a change set, you must
    #     acknowledge this capability. This includes the [AWS::Include][10]
    #     and [AWS::Serverless][11] transforms, which are macros hosted by
    #     CloudFormation.
    #
    #     If you want to update a stack from a stack template that contains
    #     macros *and* nested stacks, you must update the stack directly from
    #     the template using this capability.
    #
    #     You should only update stacks directly from a stack template that
    #     contains macros if you know what processing the macro performs.
    #
    #      Each macro relies on an underlying Lambda service function for
    #     processing stack templates. Be aware that the Lambda function owner
    #     can update the function operation without CloudFormation being
    #     notified.
    #
    #     For more information, see [Perform custom processing on
    #     CloudFormation templates with template macros][12].

    # @option params [Array<String>] :resource_types
    #   The template resource types that you have permissions to work with for
    #   this update stack action, such as `AWS::EC2::Instance`, `AWS::EC2::*`,
    #   or `Custom::MyCustomInstance`.
    #
    #   If the list of resource types doesn't include a resource that you're
    #   updating, the stack update fails. By default, CloudFormation grants
    #   permissions to all resource types. IAM uses this parameter for
    #   CloudFormation-specific condition keys in IAM policies. For more
    #   information, see [Control access with Identity and Access
    #   Management][1].

    #
    # @option params [String] :role_arn
    #   The Amazon Resource Name (ARN) of an IAM role that CloudFormation
    #   assumes to update the stack. CloudFormation uses the role's
    #   credentials to make calls on your behalf. CloudFormation always uses
    #   this role for all future operations on the stack. Provided that users
    #   have permission to operate on the stack, CloudFormation uses this role
    #   even if the users don't have permission to pass it. Ensure that the
    #   role grants least privilege.
    #
    #   If you don't specify a value, CloudFormation uses the role that was
    #   previously associated with the stack. If no role is available,
    #   CloudFormation uses a temporary session that is generated from your
    #   user credentials.
    #
    # @option params [Types::RollbackConfiguration] :rollback_configuration
    #   The rollback triggers for CloudFormation to monitor during stack
    #   creation and updating operations, and for the specified monitoring
    #   period afterwards.
    #
    # @option params [String] :stack_policy_body
    #   Structure that contains a new stack policy body. You can specify
    #   either the `StackPolicyBody` or the `StackPolicyURL` parameter, but
    #   not both.
    #
    #   You might update the stack policy, for example, in order to protect a
    #   new resource that you created during a stack update. If you don't
    #   specify a stack policy, the current policy that is associated with the
    #   stack is unchanged.
    #
    # @option params [String] :stack_policy_url
    #   Location of a file that contains the updated stack policy. The URL
    #   must point to a policy (max size: 16KB) located in an S3 bucket in the
    #   same Region as the stack. The location for an Amazon S3 bucket must
    #   start with `https://`. URLs from S3 static websites are not supported.
    #
    #   You can specify either the `StackPolicyBody` or the `StackPolicyURL`
    #   parameter, but not both.
    #
    #   You might update the stack policy, for example, in order to protect a
    #   new resource that you created during a stack update. If you don't
    #   specify a stack policy, the current policy that is associated with the
    #   stack is unchanged.
    #
    # @option params [Array<String>] :notification_arns
    #   Amazon Simple Notification Service topic Amazon Resource Names (ARNs)
    #   that CloudFormation associates with the stack. Specify an empty list
    #   to remove all notification topics.
    #
    # @option params [Array<Types::Tag>] :tags
    #   Key-value pairs to associate with this stack. CloudFormation also
    #   propagates these tags to supported resources in the stack. You can
    #   specify a maximum number of 50 tags.
    #
    #   If you don't specify this parameter, CloudFormation doesn't modify
    #   the stack's tags. If you specify an empty value, CloudFormation
    #   removes all associated tags.
    #
    # @option params [Boolean] :disable_rollback
    #   Preserve the state of previously provisioned resources when an
    #   operation fails.
    #
    #   Default: `False`
    #
    # @option params [String] :client_request_token
    #   A unique identifier for this `UpdateStack` request. Specify this token
    #   if you plan to retry requests so that CloudFormation knows that
    #   you're not attempting to update a stack with the same name. You might
    #   retry `UpdateStack` requests to ensure that CloudFormation
    #   successfully received them.
    #
    #   All events triggered by a given stack operation are assigned the same
    #   client request token, which you can use to track operations. For
    #   example, if you execute a `CreateStack` operation with the token
    #   `token1`, then all the `StackEvents` generated by that operation will
    #   have `ClientRequestToken` set as `token1`.
    #
    #   In the console, stack operations display the client request token on
    #   the Events tab. Stack operations that are initiated from the console
    #   use the token format *Console-StackOperation-ID*, which helps you
    #   easily identify the stack operation . For example, if you create a
    #   stack using the console, each stack event would be assigned the same
    #   token in the following format:
    #   `Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002`.
    #
    # @option params [Boolean] :retain_except_on_create
    #   When set to `true`, newly created resources are deleted when the
    #   operation rolls back. This includes newly created resources marked
    #   with a deletion policy of `Retain`.
    #
    #   Default: `false`

    #
    #   * To override the current value for a parameter, include the parameter
    #     and specify its value.
    #
    #   * To leave an overridden parameter set to its present value, include
    #     the parameter and specify `UsePreviousValue` as `true`. (You can't
    #     specify both a value and set `UsePreviousValue` to `true`.)
    #
    #   * To set an overridden parameter back to the value specified in the

    #     in the list.
    #
    #   * To leave all parameters set to their present values, don't specify

    #  If you need more than 50, consider the following options:
    #
    #  * *Batch processing:* If you don't want to expose your OU hierarchy,
    #   split up the operations into multiple calls with less than 50 OUs
    #   each.
    #
    # * *Parent OU strategy:* If you don't mind exposing the OU hierarchy,
    #   target a parent OU that contains all desired child OUs.
    #
    #  </note>
    #
    # @option params [required, String] :stack_set_name
    #   The name or unique ID of the StackSet that you want to update.
    #
    # @option params [String] :description
    #   A brief description of updates that you are making.
    #
    # @option params [String] :template_body
    #   The structure that contains the template body, with a minimum length
    #   of 1 byte and a maximum length of 51,200 bytes.
    #
    #   Conditional: You must specify only one of the following parameters:
    #   `TemplateBody` or `TemplateURL`—or set `UsePreviousTemplate` to true.
    #
    # @option params [String] :template_url
    #   The URL of a file that contains the template body. The URL must point
    #   to a template (maximum size: 1 MB) that is located in an Amazon S3
    #   bucket or a Systems Manager document. The location for an Amazon S3
    #   bucket must start with `https://`. S3 static website URLs are not
    #   supported.
    #
    #   Conditional: You must specify only one of the following parameters:
    #   `TemplateBody` or `TemplateURL`—or set `UsePreviousTemplate` to true.
    #
    # @option params [Boolean] :use_previous_template
    #   Use the existing template that's associated with the StackSet that
    #   you're updating.
    #
    #   Conditional: You must specify only one of the following parameters:
    #   `TemplateBody` or `TemplateURL`—or set `UsePreviousTemplate` to true.
    #
    # @option params [Array<Types::Parameter>] :parameters
    #   A list of input parameters for the StackSet template.
    #
    # @option params [Array<String>] :capabilities
    #   In some cases, you must explicitly acknowledge that your stack
    #   template contains certain capabilities in order for CloudFormation to
    #   update the StackSet and its associated stack instances.
    #
    #   * `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`
    #
    #     Some stack templates might include resources that can affect
    #     permissions in your Amazon Web Services account, for example, by
    #     creating new IAM users. For those stacks sets, you must explicitly
    #     acknowledge this by specifying one of these capabilities.
    #
    #     The following IAM resources require you to specify either the
    #     `CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.
    #
    #     * If you have IAM resources, you can specify either capability.
    #
    #     * If you have IAM resources with custom names, you *must* specify
    #       `CAPABILITY_NAMED_IAM`.
    #
    #     * If you don't specify either of these capabilities, CloudFormation
    #       returns an `InsufficientCapabilities` error.
    #     If your stack template contains these resources, we recommend that
    #     you review all permissions associated with them and edit their
    #     permissions if necessary.
    #
    #     * [AWS::IAM::AccessKey][1]
    #
    #     * [AWS::IAM::Group][2]
    #
    #     * [AWS::IAM::InstanceProfile][3]
    #
    #     * [AWS::IAM::Policy][4]
    #
    #     * [AWS::IAM::Role][5]
    #
    #     * [AWS::IAM::User][6]
    #
    #     * [AWS::IAM::UserToGroupAddition][7]
    #     For more information, see [Acknowledging IAM resources in
    #     CloudFormation templates][8].
    #
    #   * `CAPABILITY_AUTO_EXPAND`
    #
    #     Some templates reference macros. If your StackSet template
    #     references one or more macros, you must update the StackSet directly
    #     from the processed template, without first reviewing the resulting
    #     changes in a change set. To update the StackSet directly, you must
    #     acknowledge this capability. For more information, see [Perform
    #     custom processing on CloudFormation templates with template
    #     macros][9].
    #
    #     StackSets with service-managed permissions do not currently support
    #     the use of macros in templates. (This includes the
    #     [AWS::Include][10] and [AWS::Serverless][11] transforms, which are
    #     macros hosted by CloudFormation.) Even if you specify this
    #     capability for a StackSet with service-managed permissions, if you
    #     reference a macro in your template the StackSet operation will fail.

    #
    # @option params [Array<Types::Tag>] :tags
    #   The key-value pairs to associate with this StackSet and the stacks
    #   created from it. CloudFormation also propagates these tags to
    #   supported resources that are created in the stacks. You can specify a
    #   maximum number of 50 tags.
    #
    #   If you specify tags for this parameter, those tags replace any list of
    #   tags that are currently associated with this StackSet. This means:
    #
    #   * If you don't specify this parameter, CloudFormation doesn't modify
    #     the stack's tags.
    #
    #   * If you specify *any* tags using this parameter, you must specify
    #     *all* the tags that you want associated with this StackSet, even
    #     tags you've specified before (for example, when creating the
    #     StackSet or during a previous update of the StackSet.). Any tags
    #     that you don't include in the updated list of tags are removed from
    #     the StackSet, and therefore from the stacks and resources as well.
    #
    #   * If you specify an empty value, CloudFormation removes all currently
    #     associated tags.
    #
    #   If you specify new tags as part of an `UpdateStackSet` action,
    #   CloudFormation checks to see if you have the required IAM permission
    #   to tag resources. If you omit tags that are currently associated with
    #   the StackSet from the list of tags you specify, CloudFormation assumes
    #   that you want to remove those tags from the StackSet, and checks to
    #   see if you have permission to untag resources. If you don't have the
    #   necessary permission(s), the entire `UpdateStackSet` action fails with
    #   an `access denied` error, and the StackSet is not updated.
    #
    # @option params [Types::StackSetOperationPreferences] :operation_preferences
    #   Preferences for how CloudFormation performs this StackSet operation.
    #
    # @option params [String] :administration_role_arn
    #   \[Self-managed permissions\] The Amazon Resource Name (ARN) of the IAM
    #   role to use to update this StackSet.
    #
    #   Specify an IAM role only if you are using customized administrator
    #   roles to control which users or groups can manage specific StackSets
    #   within the same administrator account. For more information, see
    #   [Grant self-managed permissions][1] in the *CloudFormation User
    #   Guide*.
    #
    #   If you specified a customized administrator role when you created the
    #   StackSet, you must specify a customized administrator role, even if it
    #   is the same customized administrator role used with this StackSet
    #   previously.
    #
    #
    #
    #   [1]: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-prereqs-self-managed.html
    #
    # @option params [String] :execution_role_name
    #   \[Self-managed permissions\] The name of the IAM execution role to use
    #   to update the stack set. If you do not specify an execution role,
    #   CloudFormation uses the `AWSCloudFormationStackSetExecutionRole` role
    #   for the StackSet operation.
    #
    #   Specify an IAM role only if you are using customized execution roles
    #   to control which stack resources users and groups can include in their
    #   StackSets.
    #
    #   If you specify a customized execution role, CloudFormation uses that
    #   role to update the stack. If you do not specify a customized execution
    #   role, CloudFormation performs the update using the role previously
    #   associated with the StackSet, so long as you have permissions to
    #   perform operations on the StackSet.
    #
    # @option params [Types::DeploymentTargets] :deployment_targets
    #   \[Service-managed permissions\] The Organizations accounts in which to
    #   update associated stack instances.
    #
    #   To update all the stack instances associated with this StackSet, do
    #   not specify `DeploymentTargets` or `Regions`.
    #
    #   If the StackSet update includes changes to the template (that is, if
    #   `TemplateBody` or `TemplateURL` is specified), or the `Parameters`,
    #   CloudFormation marks all stack instances with a status of `OUTDATED`
    #   prior to updating the stack instances in the specified accounts and
    #   Amazon Web Services Regions. If the StackSet update doesn't include
    #   changes to the template or parameters, CloudFormation updates the
    #   stack instances in the specified accounts and Regions, while leaving
    #   all other stack instances with their existing stack instance status.
    #
    # @option params [String] :permission_model
    #   Describes how the IAM roles required for StackSet operations are
    #   created. You cannot modify `PermissionModel` if there are stack
    #   instances associated with your stack set.
    #
    #   * With `self-managed` permissions, you must create the administrator
    #     and execution roles required to deploy to target accounts. For more
    #     information, see [Grant self-managed permissions][1].
    #
    #   * With `service-managed` permissions, StackSets automatically creates
    #     the IAM roles required to deploy to accounts managed by
    #     Organizations. For more information, see [Activate trusted access
    #     for StackSets with Organizations][2].

    #
    # @option params [Types::AutoDeployment] :auto_deployment
    #   \[Service-managed permissions\] Describes whether StackSets
    #   automatically deploys to Organizations accounts that are added to a
    #   target organization or organizational unit (OU). For more information,
    #   see [Enable or disable automatic deployments for StackSets in
    #   Organizations][1] in the *CloudFormation User Guide*.

    #
    # @option params [String] :operation_id
    #   The unique ID for this StackSet operation.
    #
    #   The operation ID also functions as an idempotency token, to ensure
    #   that CloudFormation performs the StackSet operation only once, even if
    #   you retry the request multiple times. You might retry StackSet
    #   operation requests to ensure that CloudFormation successfully received
    #   them.
    #
    #   If you don't specify an operation ID, CloudFormation generates one
    #   automatically.
    #
    #   Repeating this StackSet operation with a new operation ID retries all
    #   stack instances whose status is `OUTDATED`.
    #
    #   **A suitable default value is auto-generated.** You should normally
    #   not need to pass this option.**
    #
    # @option params [Array<String>] :accounts
    #   \[Self-managed permissions\] The accounts in which to update
    #   associated stack instances. If you specify accounts, you must also
    #   specify the Amazon Web Services Regions in which to update StackSet
    #   instances.
    #
    #   To update *all* the stack instances associated with this StackSet,
    #   don't specify the `Accounts` or `Regions` properties.
    #
    #   If the StackSet update includes changes to the template (that is, if
    #   the `TemplateBody` or `TemplateURL` properties are specified), or the
    #   `Parameters` property, CloudFormation marks all stack instances with a
    #   status of `OUTDATED` prior to updating the stack instances in the
    #   specified accounts and Amazon Web Services Regions. If the StackSet
    #   update does not include changes to the template or parameters,
    #   CloudFormation updates the stack instances in the specified accounts
    #   and Amazon Web Services Regions, while leaving all other stack
    #   instances with their existing stack instance status.
    #
    # @option params [Array<String>] :regions
    #   The Amazon Web Services Regions in which to update associated stack
    #   instances. If you specify Regions, you must also specify accounts in
    #   which to update StackSet instances.
    #
    #   To update *all* the stack instances associated with this StackSet, do
    #   not specify the `Accounts` or `Regions` properties.
    #
    #   If the StackSet update includes changes to the template (that is, if
    #   the `TemplateBody` or `TemplateURL` properties are specified), or the
    #   `Parameters` property, CloudFormation marks all stack instances with a
    #   status of `OUTDATED` prior to updating the stack instances in the
    #   specified accounts and Regions. If the StackSet update does not
    #   include changes to the template or parameters, CloudFormation updates
    #   the stack instances in the specified accounts and Regions, while
    #   leaving all other stack instances with their existing stack instance
    #   status.
    #
    # @option params [String] :call_as
    #   \[Service-managed permissions\] Specifies whether you are acting as an
    #   account administrator in the organization's management account or as
    #   a delegated administrator in a member account.
    #
    #   By default, `SELF` is specified. Use `SELF` for StackSets with
    #   self-managed permissions.
    #
    #   * If you are signed in to the management account, specify `SELF`.
    #
    #   * If you are signed in to a delegated administrator account, specify
    #     `DELEGATED_ADMIN`.
    #
    #     Your Amazon Web Services account must be registered as a delegated
    #     administrator in the management account. For more information, see
    #     [Register a delegated administrator][1] in the *CloudFormation User
    #     Guide*.

    # Polls an API operation until a resource enters a desired state.
    #
    # ## Basic Usage
    #
    # A waiter will call an API operation until:
    #
    # * It is successful
    # * It enters a terminal state
    # * It makes the maximum number of attempts
    #
    # In between attempts, the waiter will sleep.
    #
    #     # polls in a loop, sleeping between attempts
    #     client.wait_until(waiter_name, params)
    #
    # ## Configuration
    #
    # You can configure the maximum number of polling attempts, and the
    # delay (in seconds) between each polling attempt. You can pass
    # configuration as the final arguments hash.
    #
    #     # poll for ~25 seconds
    #     client.wait_until(waiter_name, params, {
    #       max_attempts: 5,
    #       delay: 5,
    #     })
    #
    # ## Callbacks
    #
    # You can be notified before each polling attempt and before each
    # delay. If you throw `:success` or `:failure` from these callbacks,
    # it will terminate the waiter.
    #
    #     started_at = Time.now
    #     client.wait_until(waiter_name, params, {
    #
    #       # disable max attempts
    #       max_attempts: nil,
    #
    #       # poll for 1 hour, instead of a number of attempts
    #       before_wait: -> (attempts, response) do
    #         throw :failure if Time.now - started_at > 3600
    #       end
    #     })
    #
    # ## Handling Errors
    #
    # When a waiter is unsuccessful, it will raise an error.
    # All of the failure errors extend from
    # {Aws::Waiters::Errors::WaiterFailed}.
    #
    #     begin
    #       client.wait_until(...)
    #     rescue Aws::Waiters::Errors::WaiterFailed
    #       # resource did not enter the desired state in time
    #     end
