"""Represents a client connection that connects to Discord.
This class is used to interact with the Discord WebSocket and API.

.. _deque: https://docs.python.org/3.4/library/collections.html#collections.deque
.. _event loop: https://docs.python.org/3/library/asyncio-eventloops.html
Parameters
----------
max_messages : Optional[int]
The maximum number of messages to store in :attr:`messages`.
This defaults to 5000. Passing in `None` or a value less than 100
will use the default instead of the passed in value.
loop : Optional[event loop].
The `event loop`_ to use for asynchronous operations. Defaults to ``None``,
in which case the default event loop is used via ``asyncio.get_event_loop()``.
Attributes
-----------
user : Optional[:class:`User`]
Represents the connected client. None if not logged in.
servers : list of :class:`Server`
The servers that the connected client is a member of.
private_channels : list of :class:`PrivateChannel`
The private channels that the connected client is participating on.
messages
A deque_ of :class:`Message` that the client has received from all
servers and private messages. The number of messages stored in this
deque is controlled by the ``max_messages`` parameter.
email
The email used to login. This is only set if login is successful,
otherwise it's None.
gateway
The websocket gateway the client is currently connected to. Could be None.
loop
The `event loop`_ that the client uses for HTTP requests and websocket operations.
