"""Restart the Client.

This method will first call :meth:`~pyrogram.Client.stop` and then :meth:`~pyrogram.Client.start` in a row in

order to restart a client using a single method.

Parameters:

block (``bool``, *optional*):

Blocks the code execution until the client has been restarted. It is useful with ``block=False`` in case

you want to restart the own client *within* an handler in order not to cause a deadlock.

Defaults to True.

Returns:

:obj:`~pyrogram.Client`: The restarted client itself.

Raises:

ConnectionError: In case you try to restart a stopped Client.

Example:

.. code-block:: python

:emphasize-lines: 8

from pyrogram import Client

app = Client("my_account")

app.start()

... # Call API methods

app.restart()

... # Call other API methods

app.stop()
