"""Iterate through a user's dialogs sequentially.
This convenience method does the same as repeatedly calling :meth:`~Client.get_dialogs` in a loop, thus saving
you from the hassle of setting up boilerplate code. It is useful for getting the whole dialogs list with a
single call.
Parameters:
limit (``str``, *optional*):
Limits the number of dialogs to be retrieved.
By default, no limit is applied and all dialogs are returned.
offset_date (``int``):
The offset date in Unix time taken from the top message of a :obj:`Dialog`.
Defaults to 0 (most recent dialog).
Returns:
``Generator``: A generator yielding :obj:`Dialog` objects.
Raises:
RPCError: In case of a Telegram RPC error.
