class Dialog:
"""
Custom class that encapsulates a dialog (an open "conversation" with
someone, a group or a channel) providing an abstraction to easily
access the input version/normal entity/message etc. The library will
return instances of this class when calling :meth:`.get_dialogs()`.
Args:
dialog (:tl:`Dialog`):
The original ``Dialog`` instance.
pinned (`bool`):
Whether this dialog is pinned to the top or not.
message (`Message <telethon.tl.custom.message.Message>`):
The last message sent on this dialog. Note that this member
will not be updated when new messages arrive, it's only set
on creation of the instance.
date (`datetime`):
The date of the last message sent on this dialog.
entity (`entity`):
The entity that belongs to this dialog (user, chat or channel).
input_entity (:tl:`InputPeer`):
Input version of the entity.
id (`int`):
The marked ID of the entity, which is guaranteed to be unique.
name (`str`):
Display name for this dialog. For chats and channels this is
their title, and for users it's "First-Name Last-Name".
title (`str`):
Alias for `name`.
unread_count (`int`):
How many messages are currently unread in this dialog. Note that
this value won't update when new messages arrive.
unread_mentions_count (`int`):
How many mentions are currently unread in this dialog. Note that
this value won't update when new messages arrive.
draft (`telethon.tl.custom.draft.Draft`):
The draft object in this dialog. It will not be ``None``,
so you can call ``draft.set_message(...)``.
is_user (`bool`):
``True`` if the `entity` is a :tl:`User`.
is_group (`bool`):
``True`` if the `entity` is a :tl:`Chat`
or a :tl:`Channel` megagroup.
is_channel (`bool`):
``True`` if the `entity` is a :tl:`Channel`.
