user ID / device ID pair. Thus, applying a limit (of messages to return) when working
with a sliding window of stream IDs is only possible when querying messages of a
single user device.
Finally, note that device IDs are not unique across users.
Args:
user_ids: The user IDs to filter device messages by.
from_stream_id: The lower boundary of stream id to filter with (exclusive).
to_stream_id: The upper boundary of stream id to filter with (inclusive).
device_id: A device ID to query to-device messages for. If not provided, to-device
messages from all device IDs for the given user IDs will be queried. May not be
provided if `user_ids` contains more than one entry.
limit: The maximum number of to-device messages to return. Can only be used when
passing a single user ID / device ID tuple.
Returns:
A tuple containing:
* A dict of (user_id, device_id) -> list of to-device messages
* The last-processed stream ID. If this is less than `to_stream_id`, then
there may be more messages to retrieve. If `limit` is not set, then this
is always equal to 'to_stream_id'.
