class RegistrationServiceGrpcAsyncIOTransport(RegistrationServiceTransport):
    """gRPC AsyncIO backend transport for RegistrationService.

    Service Directory API for registering services. It defines the
    following resource model:

    -  The API has a collection of
       [Namespace][google.cloud.servicedirectory.v1beta1.Namespace]
       resources, named ``projects/*/locations/*/namespaces/*``.

    -  Each Namespace has a collection of
       [Service][google.cloud.servicedirectory.v1beta1.Service]
       resources, named
       ``projects/*/locations/*/namespaces/*/services/*``.

    -  Each Service has a collection of
       [Endpoint][google.cloud.servicedirectory.v1beta1.Endpoint]
       resources, named
       ``projects/*/locations/*/namespaces/*/services/*/endpoints/*``.

    This class defines the same methods as the primary client, so the
    primary client can load the underlying transport implementation
    and call it.

    It sends protocol buffers over the wire using gRPC (which is built on
    top of HTTP/2); the ``grpcio`` package must be installed.
