metadata=None,
):
"""
Deletes the topic with the given name. Returns ``NOT_FOUND`` if the
topic does not exist. After a topic is deleted, a new topic may be
created with the same name; this is an entirely new topic with none of
the old configuration or subscriptions. Existing subscriptions to this
topic are not deleted, but their ``topic`` field is set to
``_deleted-topic_``.
Example:
>>> from google.cloud import pubsub_v1
>>>
>>> client = pubsub_v1.PublisherClient()
>>>
>>> topic = client.topic_path('[PROJECT]', '[TOPIC]')
>>>
>>> client.delete_topic(topic)
Args:
topic (str): Name of the topic to delete. Format is
``projects/{project}/topics/{topic}``.
retry (Optional[google.api_core.retry.Retry]): A retry object used
to retry requests. If ``None`` is specified, requests will not
be retried.
timeout (Optional[float]): The amount of time, in seconds, to wait
for the request to complete. Note that if ``retry`` is
specified, the timeout applies to each individual attempt.
metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
that is provided to the method.
Raises:
google.api_core.exceptions.GoogleAPICallError: If the request
failed for any reason.
google.api_core.exceptions.RetryError: If the request failed due
to a retryable error and retry attempts failed.
ValueError: If the parameters are invalid.
