                   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 (defined by IAM or configured by users).
                   A binding can optionally specify a condition, which
                   is a logic expression that further constrains the
                   role binding based on attributes about the request
                   and/or target resource.

        service only).

        Args:
            request (Union[google.iam.v1.iam_policy_pb2.SetIamPolicyRequest, dict]):
                The request object. Request message for `SetIamPolicy`
                method.
            retry (google.api_core.retry.Retry): Designation of what errors, if any,
                should be retried.
            timeout (float): The timeout for this request.
            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.iam.v1.policy_pb2.Policy:
                Defines an Identity and Access Management (IAM) policy. It is used to
                   specify access control policies for Cloud Platform
                   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 (defined by IAM or configured by users).
                   A binding can optionally specify a condition, which
                   is a logic expression that further constrains the
                   role binding based on attributes about the request
                   and/or target resource.
