    Attributes
    -----------
    tts: :class:`bool`
        Specifies if the message was done with text-to-speech.
        This can only be accurately received in :func:`on_message` due to
        a discord limitation.
    type: :class:`MessageType`
        The type of message. In most cases this should not be checked, but it is helpful
        in cases where it might be a system message for :attr:`system_content`.
    author: Union[:class:`Member`, :class:`abc.User`]
        A :class:`Member` that sent the message. If :attr:`channel` is a
        private channel or the user has the left the guild, then it is a :class:`User` instead.
    content: :class:`str`
        The actual contents of the message.
        If :attr:`Intents.message_content` is not enabled this will always be an empty string
        unless the bot is mentioned or the message is a direct message.
    nonce: Optional[Union[:class:`str`, :class:`int`]]
        The value used by the discord guild and the client to verify that the message is successfully sent.
        This is not stored long term within Discord's servers and is only used ephemerally.
    embeds: List[:class:`Embed`]
        A list of embeds the message has.
        If :attr:`Intents.message_content` is not enabled this will always be an empty list
        unless the bot is mentioned or the message is a direct message.
    channel: Union[:class:`TextChannel`, :class:`StageChannel`, :class:`VoiceChannel`, :class:`Thread`, :class:`DMChannel`, :class:`GroupChannel`, :class:`PartialMessageable`]
        The :class:`TextChannel` or :class:`Thread` that the message was sent from.
        Could be a :class:`DMChannel` or :class:`GroupChannel` if it's a private message.
    reference: Optional[:class:`~discord.MessageReference`]
        The message that this message references. This is only applicable to
        message replies (:attr:`MessageType.reply`), crossposted messages created by
        a followed channel integration, forwarded messages, and messages of type:

        - :attr:`MessageType.pins_add`
        - :attr:`MessageType.channel_follow_add`
        - :attr:`MessageType.thread_created`
        - :attr:`MessageType.thread_starter_message`
        - :attr:`MessageType.poll_result`
        - :attr:`MessageType.context_menu_command`

        .. versionadded:: 1.5

    mention_everyone: :class:`bool`
        Specifies if the message mentions everyone.

        .. note::

            This does not check if the ``@everyone`` or the ``@here`` text is in the message itself.
            Rather this boolean indicates if either the ``@everyone`` or the ``@here`` text is in the message
            **and** it did end up mentioning.
    mentions: List[:class:`abc.User`]
        A list of :class:`Member` that were mentioned. If the message is in a private message
        then the list will be of :class:`User` instead. For messages that are not of type
        :attr:`MessageType.default`\, this array can be used to aid in system messages.
        For more information, see :attr:`system_content`.

        .. warning::

            The order of the mentions list is not in any particular order so you should
            not rely on it. This is a Discord limitation, not one with the library.
    channel_mentions: List[Union[:class:`abc.GuildChannel`, :class:`Thread`]]
        A list of :class:`abc.GuildChannel` or :class:`Thread` that were mentioned. If the message is
        in a private message then the list is always empty.

        then the list is always empty.

        A list of attachments given to a message.
        If :attr:`Intents.message_content` is not enabled this will always be an empty list

        Edits the message.

        The content must be able to be transformed into a string via ``str(content)``.

        .. versionchanged:: 1.3
            The ``suppress`` keyword-only parameter was added.

        .. versionchanged:: 2.0
            Edits are no longer in-place, the newly edited message is returned instead.

        .. versionchanged:: 2.0
            This function will now raise :exc:`TypeError` instead of
            ``InvalidArgument``.

        Parameters
        -----------
        content: Optional[:class:`str`]
            The new content to replace the message with.
            Could be ``None`` to remove the content.
        embed: Optional[:class:`Embed`]
            The new embed to replace the original with.
            Could be ``None`` to remove the embed.
        embeds: List[:class:`Embed`]
            The new embeds to replace the original with. Must be a maximum of 10.
            To remove all embeds ``[]`` should be passed.

            .. versionadded:: 2.0
        attachments: List[Union[:class:`Attachment`, :class:`File`]]
            A list of attachments to keep in the message as well as new files to upload. If ``[]`` is passed
            then all attachments are removed.

            .. note::

                New files will always appear after current attachments.

            .. versionadded:: 2.0
        suppress: :class:`bool`
            Whether to suppress embeds for the message. This removes
            all the embeds if set to ``True``. If set to ``False``
            this brings the embeds back if they were suppressed.
            Using this parameter requires :attr:`~.Permissions.manage_messages`.
        delete_after: Optional[:class:`float`]
            If provided, the number of seconds to wait in the background
            before deleting the message we just edited. If the deletion fails,
            then it is silently ignored.
        allowed_mentions: Optional[:class:`~discord.AllowedMentions`]
            Controls the mentions being processed in this message. If this is
            passed, then the object is merged with :attr:`~discord.Client.allowed_mentions`.
            The merging behaviour only overrides attributes that have been explicitly passed
            to the object, otherwise it uses the attributes set in :attr:`~discord.Client.allowed_mentions`.
            If no object is passed at all then the defaults given by :attr:`~discord.Client.allowed_mentions`
            are used instead.

            .. versionadded:: 1.4
        view: Optional[:class:`~discord.ui.View`]
            The updated view to update this message with. If ``None`` is passed then
            the view is removed.
