 """ Streams RoomInstance records from the API as a generator stream. This operation lazily loads records as efficiently as possible until the limit is reached. The results are returned as a generator, so this operation is memory efficient. :param RoomInstance.RoomStatus status: Only show Rooms with the given status. :param unicode unique_name: Only show Rooms with the provided Name. :param datetime date_created_after: Only show Rooms that started on or after this date, given as YYYY-MM-DD. :param datetime date_created_before: Only show Rooms that started before this date, given as YYYY-MM-DD. :param int limit: Upper limit for the number of records to return. stream() guarantees to never return more than limit. Default is no limit :param int page_size: Number of records to fetch per request, when not set will use the default value of 50 records. If no page_size is defined but a limit is defined, stream() will attempt to read the limit with the most efficient page size, i.e. min(limit, 1000) :returns: Generator that will yield up to limit results :rtype: list[twilio.rest.video.v1.room.RoomInstance] """
