message (:obj:`Message`):

This is the original ``Message`` object.

input_chat (:obj:`InputPeer`):
|
||||
This is the input chat (private, group, megagroup or channel)
|
||||
to which the message was sent. This doesn't have the title or
|

anything, but is useful if you don't need those to avoid
|
||||
further requests.
|
||||
|
||||
Note that this might not be available if the library can't
|
||||
find the input chat.

|

most up to date version of the chat, so use with care as

there is no caching besides local caching yet.

True if the message was sent as a private message.

True if the message was sent on a megagroup or channel.
|
||||
|
||||
input_sender (:obj:`InputPeer`):
|
||||
This is the input version of the user who sent the message.
|
||||
Similarly to ``input_chat``, this doesn't have things like
|
||||
username or similar, but still useful in some cases.
|
||||
|
||||
Note that this might not be available if the library can't

find the input chat.

``input_sender`` needs to be available (often the case).

text (:obj:`str`):

The message text, markdown-formatted.

raw_text (:obj:`str`):
|

The raw message text, ignoring any formatting.

The unmodified ``MessageFwdHeader``, if present.

Whether the message is outgoing (i.e. you sent it from
