class Restart:

async def restart(self: "hydrogram.Client", block: bool = True):

"""Restart the Client.

This method will first call :meth:`~hydrogram.Client.stop` and then :meth:`~hydrogram.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:`~hydrogram.Client`: The restarted client itself.

Raises:

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

Example:

.. code-block:: python

from hydrogram import Client

app = Client("my_account")

async def main():

await app.start()

... # Invoke API methods

await app.restart()

... # Invoke other API methods

await app.stop()

app.run(main())
