class ChatPermissions(TelegramObject):
"""Describes actions that a non-administrator user is allowed to take in a chat.
Objects of this class are comparable in terms of equality. Two objects of this class are
considered equal, if their :attr:`can_send_messages`, :attr:`can_send_media_messages`,
:attr:`can_send_polls`, :attr:`can_send_other_messages`, :attr:`can_add_web_page_previews`,
:attr:`can_change_info`, :attr:`can_invite_users` and :attr:`can_pin_messages` are equal.
Note:
Though not stated explicitly in the official docs, Telegram changes not only the
permissions that are set, but also sets all the others to :obj:`False`. However, since not
documented, this behaviour may change unbeknown to PTB.
Args:
can_send_messages (:obj:`bool`, optional): :obj:`True`, if the user is allowed to send text
messages, contacts, locations and venues.
can_send_media_messages (:obj:`bool`, optional): :obj:`True`, if the user is allowed to
send audios, documents, photos, videos, video notes and voice notes, implies
:attr:`can_send_messages`.
can_send_polls (:obj:`bool`, optional): :obj:`True`, if the user is allowed to send polls,
implies :attr:`can_send_messages`.
can_send_other_messages (:obj:`bool`, optional): :obj:`True`, if the user is allowed to
send animations, games, stickers and use inline bots, implies
:attr:`can_send_media_messages`.
can_add_web_page_previews (:obj:`bool`, optional): :obj:`True`, if the user is allowed to
add web page previews to their messages, implies :attr:`can_send_media_messages`.
can_change_info (:obj:`bool`, optional): :obj:`True`, if the user is allowed to change the
chat title, photo and other settings. Ignored in public supergroups.
can_invite_users (:obj:`bool`, optional): :obj:`True`, if the user is allowed to invite new
users to the chat.
can_pin_messages (:obj:`bool`, optional): :obj:`True`, if the user is allowed to pin
messages. Ignored in public supergroups.
Attributes:
can_send_messages (:obj:`bool`): Optional. :obj:`True`, if the user is allowed to send text
messages, contacts, locations and venues.
can_send_media_messages (:obj:`bool`): Optional. :obj:`True`, if the user is allowed to
send audios, documents, photos, videos, video notes and voice notes, implies
:attr:`can_send_messages`.
can_send_polls (:obj:`bool`): Optional. :obj:`True`, if the user is allowed to send polls,
implies :attr:`can_send_messages`.
can_send_other_messages (:obj:`bool`): Optional. :obj:`True`, if the user is allowed to
send animations, games, stickers and use inline bots, implies
:attr:`can_send_media_messages`.
can_add_web_page_previews (:obj:`bool`): Optional. :obj:`True`, if the user is allowed to
add web page previews to their messages, implies :attr:`can_send_media_messages`.
can_change_info (:obj:`bool`): Optional. :obj:`True`, if the user is allowed to change the
chat title, photo and other settings. Ignored in public supergroups.
can_invite_users (:obj:`bool`): Optional. :obj:`True`, if the user is allowed to invite
new users to the chat.
