                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.

                This corresponds to the ``resource`` field
                on the ``request`` instance; if ``request`` is provided, this
                should not be set.
            permissions (:class:`Sequence[str]`):
                The set of permissions to check for the ``resource``.
                Permissions with wildcards (such as '*' or 'storage.*')
                are not allowed. For more information see `IAM
                Overview <https://cloud.google.com/iam/docs/overview#permissions>`__.

                on the ``request`` instance; if ``request`` is provided, this
                should not be set.

            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.
