Args:

callback (:term:`coroutine function`): The callback function for this handler. Will be

this handler. Callback signature::

The return value of the callback is usually ignored except for the special case of

block (:obj:`bool`, optional): Determines whether the return value of the callback should

is used on :attr:`telegram.ChosenInlineResult.result_id` to determine if an update

should be handled by this handler. This is accessible in the callback as
