"""
Handler class to handle telegram messages. Messages are Telegram Updates
that do not contain a command. They might contain text, media or status
updates.
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``
