"""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.
|
|
|
|
offset_date (``int``):
|
|
The offset date in Unix time taken from the top message of a :obj:`~pyrogram.types.Dialog`.
|
|
Defaults to 0 (most recent dialog).
|
|
|
|
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)
