"""The Poll handler class. Used to handle polls updates.
It is intended to be used with :meth:`~hydrogram.Client.add_handler`
For a nicer way to register this handler, have a look at the
:meth:`~hydrogram.Client.on_poll` decorator.
Parameters:
callback (``Callable``):
Pass a function that will be called when a new poll update arrives. It takes *(client, poll)*
as positional arguments (look at the section below for a detailed description).
filters (:obj:`Filters`):
Pass one or more filters to allow only a subset of polls to be passed
in your callback function.
Other parameters:
client (:obj:`~hydrogram.Client`):
The Client itself, useful when you want to call other API methods inside the poll handler.
poll (:obj:`~hydrogram.types.Poll`):
The received poll.
