      # An Identity and Access Management (IAM) policy, which specifies access
      # controls for Google Cloud resources.
      # A `Policy` is a collection of `bindings`. A `binding` binds one or more
      # `members` to a single `role`. Members can be user accounts, service accounts,
      # Google groups, and domains (such as G Suite). A `role` is a named list of
      # permissions; each `role` can be an IAM predefined role or a user-created
      # custom role.
      # For some types of Google Cloud resources, a `binding` can also specify a
      # `condition`, which is a logical expression that allows access to a resource
      # only if the expression evaluates to `true`. A condition can add constraints
      # based on attributes of the request, the resource, or both. To learn which
      # resources support conditions in their IAM policies, see the
      # [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-
      # policies).
