Sets the channel specific permission overwrites for a target in the

The ``target`` parameter should either be a :class:`~discord.Member` or a
:class:`~discord.Role` that belongs to guild.
The ``overwrite`` parameter, if given, must either be ``None`` or

Examples

Whether to move the channel to the end of the

before: :class:`~discord.abc.Snowflake`

This is mutually exclusive with ``beginning``, ``end``, and ``after``.
after: :class:`~discord.abc.Snowflake`
Whether to move the channel after the given channel.
This is mutually exclusive with ``beginning``, ``end``, and ``before``.
offset: :class:`int`
The number of channels to offset the move by. For example,
an offset of ``2`` with ``beginning=True`` would move
it 2 after the beginning. A positive number moves it below
while a negative number moves it above. Note that this
number is relative and computed after the ``beginning``,
``end``, ``before``, and ``after`` parameters.
category: Optional[:class:`~discord.abc.Snowflake`]
The category to move this channel under.
If ``None`` is given then it moves it out of the category.
This parameter is ignored if moving a category channel.
sync_permissions: :class:`bool`

Parameters
------------

The content of the message to send.

Indicates if the message should be sent using text-to-speech.
embed: :class:`~discord.Embed`
The rich embed for the content.
embeds: List[:class:`~discord.Embed`]
A list of embeds to upload. Must be a maximum of 10.
.. versionadded:: 2.0
file: :class:`~discord.File`
The file to upload.
files: List[:class:`~discord.File`]
A list of files to upload. Must be a maximum of 10.
nonce: :class:`int`
The nonce to use for sending this message. If the message was successfully sent,
then the message will have a nonce with this value.
delete_after: :class:`float`
If provided, the number of seconds to wait in the background
before deleting the message we just sent. If the deletion fails,
then it is silently ignored.
allowed_mentions: :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
reference: Union[:class:`~discord.Message`, :class:`~discord.MessageReference`, :class:`~discord.PartialMessage`]
A reference to the :class:`~discord.Message` to which you are referencing, this can be created using
:meth:`~discord.Message.to_reference` or passed directly as a :class:`~discord.Message`.
In the event of a replying reference, you can control whether this mentions the author of the referenced
message using the :attr:`~discord.AllowedMentions.replied_user` attribute of ``allowed_mentions`` or by
setting ``mention_author``.
.. versionadded:: 1.6
mention_author: Optional[:class:`bool`]
If set, overrides the :attr:`~discord.AllowedMentions.replied_user` attribute of ``allowed_mentions``.
.. versionadded:: 1.6
view: :class:`discord.ui.View`
A Discord UI View to add to the message.
.. versionadded:: 2.0
stickers: Sequence[Union[:class:`~discord.GuildSticker`, :class:`~discord.StickerItem`]]
A list of stickers to upload. Must be a maximum of 3.
.. versionadded:: 2.0
suppress_embeds: :class:`bool`
Whether to suppress embeds for the message. This sends the message without any embeds if set to ``True``.
.. versionadded:: 2.0
silent: :class:`bool`
Whether to suppress push and desktop notifications for the message. This will increment the mention counter
in the UI, but will not actually send a notification.
.. versionadded:: 2.2
poll: :class:`~discord.Poll`
The poll to send with this message.
.. versionadded:: 2.4
Raises
--------
~discord.HTTPException
Sending the message failed.
~discord.Forbidden
You do not have the proper permissions to send the message.
~discord.NotFound
You sent a message with the same nonce as one that has been explicitly
deleted shortly earlier.
ValueError
The ``files`` or ``embeds`` list is not of the appropriate size.
TypeError
You specified both ``file`` and ``files``,

"""|coro|
Connects to voice and creates a :class:`~discord.VoiceClient` to establish
your connection to the voice server.
This requires :attr:`~discord.Intents.voice_states`.
Parameters
-----------
timeout: :class:`float`
The timeout in seconds to wait the connection to complete.
reconnect: :class:`bool`
Whether the bot should automatically attempt
a reconnect if a part of the handshake fails
or the gateway goes down.
cls: Type[:class:`~discord.VoiceProtocol`]
A type that subclasses :class:`~discord.VoiceProtocol` to connect with.
Defaults to :class:`~discord.VoiceClient`.
self_mute: :class:`bool`
Indicates if the client should be self-muted.
.. versionadded:: 2.0
self_deaf: :class:`bool`
Indicates if the client should be self-deafened.
.. versionadded:: 2.0
Raises
-------
asyncio.TimeoutError
Could not connect to the voice channel in time.
~discord.ClientException
You are already connected to a voice channel.
~discord.opus.OpusNotLoaded
The opus library has not been loaded.
Returns
--------
:class:`~discord.VoiceProtocol`
A voice client that is fully connected to the voice server.
