"""Use this method to get the total count of messages in a chat.
|
|
|
|
.. note::
|
|
|
|
Due to Telegram latest internal changes, the server can't reliably find anymore the total count of messages
|
|
a **private** or a **basic group** chat has with a single method call. To overcome this limitation, Pyrogram
|
|
has to iterate over all the messages. Channels and supergroups are not affected by this limitation.
|
|
|
|
Parameters:
|
|
chat_id (``int`` | ``str``):
|
|
Unique identifier (int) or username (str) of the target chat.
|
|
|
|
Returns:
|
|
``int``: On success, an integer is returned.
|
|
|
|
Raises:
|
|
RPCError: In case of a Telegram RPC error.
