Args:
|

filters (list[function]): A list of filter functions. Standard filters

can be found in the Filters class above.
|
|
| Each `function` takes ``Update`` as arg and returns ``bool``.
|
|
| All messages that match at least one of those filters will be

|
accepted. If ``bool(filters)`` evaluates to ``False``, messages are
|
|
not filtered.
|
|
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``
