"""Iterate through a user's dialogs sequentially.
This convenience method does the same as repeatedly calling :meth:`~pyrogram.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 (``int``, *optional*):
Limits the number of dialogs to be retrieved.
By default, no limit is applied and all dialogs are returned.
Returns:
``Generator``: A generator yielding :obj:`~pyrogram.types.Dialog` objects.
Example:
.. code-block:: python
# Iterate through all dialogs
for dialog in app.iter_dialogs():
print(dialog.chat.first_name or dialog.chat.title)
