"""Get the InputPeer of a known peer id.
|
|
Useful whenever an InputPeer type is required.
|
|
|
|
.. note::
|
|
|
|
This is a utility method intended to be used **only** when working with raw
|
|
:obj:`functions <pyrogram.api.functions>` (i.e: a Telegram API method you wish to use which is not
|
|
available yet in the Client class as an easy-to-use method).
|
|
|
|
Parameters:
|
|
peer_id (``int`` | ``str``):
|
|
The peer id you want to extract the InputPeer from.
|
|
Can be a direct id (int), a username (str) or a phone number (str).
|
|
|
|
Returns:
|
|
``InputPeer``: On success, the resolved peer id is returned in form of an InputPeer object.
|
|
|
|
Raises:
|
|
KeyError: In case the peer doesn't exist in the internal database.
