                through which to make calls. This argument is mutually exclusive

            page_size (int): The maximum number of resources contained in the
                underlying API response. If page streaming is performed per-
                resource, this parameter does not affect the return value. If page

            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.

                that is provided to the method.

        Returns:
            A :class:`~google.api_core.page_iterator.PageIterator` instance.

            using its `pages` property.

                that is provided to the method.
