    Args:
        interface_config (Mapping): The interface config section of the full
            gapic library config. For example, If the full configuration has
            an interface named ``google.example.v1.ExampleService`` you would
            pass in just that interface's configuration, for example
            ``gapic_config['interfaces']['google.example.v1.ExampleService']``.

            configuration.
