 def wrap_method( func, default_retry=None, default_timeout=None, client_info=client_info.DEFAULT_CLIENT_INFO, ):
 """Wrap an RPC method with common behavior. This applies common error wrapping, retry, and timeout behavior a function. The wrapped function will take optional ``retry`` and ``timeout`` arguments. For example:: import google.api_core.gapic_v1.method from google.api_core import retry from google.api_core import timeout # The original RPC method. def get_topic(name, timeout=None):
 request = publisher_v2.GetTopicRequest(name=name) return publisher_stub.GetTopic(request, timeout=timeout) default_retry = retry.Retry(deadline=60) default_timeout = timeout.Timeout(deadline=60) wrapped_get_topic = google.api_core.gapic_v1.method.wrap_method( get_topic, default_retry) # Execute get_topic with default retry and timeout: response = wrapped_get_topic() # Execute get_topic without doing any retying but with the default # timeout: response = wrapped_get_topic(retry=None) # Execute get_topic but only retry on 5xx errors: my_retry = retry.Retry(retry.if_exception_type( exceptions.InternalServerError)) response = wrapped_get_topic(retry=my_retry) The way this works is by late-wrapping the given function with the retry and timeout decorators. Essentially, when ``wrapped_get_topic()`` is called: * ``get_topic()`` is first wrapped with the ``timeout`` into ``get_topic_with_timeout``. * ``get_topic_with_timeout`` is wrapped with the ``retry`` into ``get_topic_with_timeout_and_retry()``. * The final ``get_topic_with_timeout_and_retry`` is called passing through the ``args`` and ``kwargs``. The callstack is therefore:: method.__call__() -> Retry.__call__() -> Timeout.__call__() -> wrap_errors() -> get_topic() Note that if ``timeout`` or ``retry`` is ``None``, then they are not applied to the function. For example, ``wrapped_get_topic(timeout=None, retry=None)`` is more or less equivalent to just calling ``get_topic`` but with error re-mapping. Args: func (Callable[Any]):
 The function to wrap. It should accept an optional ``timeout`` argument. If ``metadata`` is not ``None``, it should accept a ``metadata`` argument. default_retry (Optional[google.api_core.Retry]):
 The default retry strategy. If ``None``, the method will not retry by default. default_timeout (Optional[google.api_core.Timeout]):
 The default timeout strategy. Can also be specified as an int or float. If ``None``, the method will not have timeout specified by default. client_info (Optional[google.api_core.gapic_v1.client_info.ClientInfo]):
 Client information used to create a user-agent string that's passed as gRPC metadata to the method. If unspecified, then a sane default will be used. If ``None``, then no user agent metadata will be provided to the RPC method. Returns: Callable: A new callable that takes optional ``retry`` and ``timeout`` arguments and applies the common error mapping, retry, timeout, and metadata behavior to the low-level RPC method. """
