          # API Overview
          #
          # Manages Identity and Access Management (IAM) policies.
          #
          # Any implementation of an API that offers access control features
          # implements the google.iam.v1.IAMPolicy interface.
          #
          # ## Data model
          #
          # Access control is applied when a principal (user or service account), takes
          # some action on a resource exposed by a service. Resources, identified by
          # URI-like names, are the unit of access control specification. Service
          # implementations can choose the granularity of access control and the
          # supported permissions for their resources.
          # For example one database service may allow access control to be
          # specified only at the Table level, whereas another might allow access control
          # to also be specified at the Column level.
          #
          # ## Policy Structure
          #
          # See google.iam.v1.Policy
          #
          # This is intentionally not a CRUD style API because access control policies
          # are created and deleted implicitly with the resources to which they are
          # attached.
