Args:
|

filters (telegram.ext.BaseFilter): A filter inheriting from
|
|
:class:`telegram.filters.BaseFilter`. Standard filters can be found in
|
|
:class:`telegram.filters.Filters`. Filters can be combined using bitwise
|
|
operators (& for and, | for or).
|
|
callback (function): A function that takes ``bot, update`` as
|
|
positional arguments. It will be called when the ``check_update``
|
|
has determined that an update should be processed by this handler.
|
|
allow_edited (Optional[bool]): If the handler should also accept edited messages.
|
|
Default is ``False``
|
|
pass_update_queue (optional[bool]): If the handler should be passed the
|
|
update queue as a keyword argument called ``update_queue``. It can
|
|
be used to insert updates. Default is ``False``
