class Client:
r"""Represents a client connection that connects to Discord.
This class is used to interact with the Discord WebSocket and API.
A number of options can be passed to the :class:`Client`.
Parameters
-----------
max_messages: Optional[:class:`int`]
The maximum number of messages to store in the internal message cache.
This defaults to 1000. Passing in ``None`` disables the message cache.
.. versionchanged:: 1.3
Allow disabling the message cache and change the default size to 1000.
loop: Optional[:class:`asyncio.AbstractEventLoop`]
The :class:`asyncio.AbstractEventLoop` to use for asynchronous operations.
Defaults to ``None``, in which case the default event loop is used via
:func:`asyncio.get_event_loop()`.
connector: :class:`aiohttp.BaseConnector`
The connector to use for connection pooling.
proxy: Optional[:class:`str`]
Proxy URL.
proxy_auth: Optional[:class:`aiohttp.BasicAuth`]
An object that represents proxy HTTP Basic Authorization.
shard_id: Optional[:class:`int`]
Integer starting at 0 and less than :attr:`.shard_count`.
shard_count: Optional[:class:`int`]
The total number of shards.
fetch_offline_members: :class:`bool`
Indicates if :func:`.on_ready` should be delayed to fetch all offline
members from the guilds the bot belongs to. If this is ``False``\, then
no offline members are received and :meth:`request_offline_members`
must be used to fetch the offline members of the guild.
status: Optional[:class:`.Status`]
A status to start your presence with upon logging on to Discord.
activity: Optional[:class:`.BaseActivity`]
An activity to start your presence with upon logging on to Discord.
heartbeat_timeout: :class:`float`
The maximum numbers of seconds before timing out and restarting the
WebSocket in the case of not receiving a HEARTBEAT_ACK. Useful if
processing the initial packets take too long to the point of disconnecting
you. The default timeout is 60 seconds.
guild_subscriptions: :class:`bool`
Whether to dispatching of presence or typing events. Defaults to ``True``.
.. versionadded:: 1.3
.. warning::
If this is set to ``False`` then the following features will be disabled:
- No user related updates (:func:`on_user_update` will not dispatch)
- All member related events will be disabled.
- :func:`on_member_update`
- :func:`on_member_join`
- :func:`on_member_remove`
- Typing events will be disabled (:func:`on_typing`).
- If ``fetch_offline_members`` is set to ``False`` then the user cache will not exist.
This makes it difficult or impossible to do many things, for example:
- Computing permissions
- Querying members in a voice channel via :attr:`VoiceChannel.members` will be empty.
- Most forms of receiving :class:`Member` will be
receiving :class:`User` instead, except for message events.
- :attr:`Guild.owner` will usually resolve to ``None``.
- :meth:`Guild.get_member` will usually be unavailable.
- Anything that involves using :class:`Member`.
- :attr:`users` will not be as populated.
- etc.
In short, this makes it so the only member you can reliably query is the
message author. Useful for bots that do not require any state.
assume_unsync_clock: :class:`bool`
Whether to assume the system clock is unsynced. This applies to the ratelimit handling
code. If this is set to ``True``, the default, then the library uses the time to reset
a rate limit bucket given by Discord. If this is ``False`` then your system clock is
used to calculate how long to sleep for. If this is set to ``False`` it is recommended to
sync your system clock to Google's NTP server.
.. versionadded:: 1.3

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

check: Optional[Callable[..., :class:`bool`]]
A predicate to check what to wait for. The arguments must meet the

timeout: Optional[:class:`float`]
The number of seconds to wait before timing out and raising
:exc:`asyncio.TimeoutError`.
Raises
-------

def fetch_guilds(self, *, limit=100, before=None, after=None):
"""|coro|
Retrieves an :class:`.AsyncIterator` that enables receiving your guilds.
.. note::
Using this, you will only receive :attr:`.Guild.owner`, :attr:`.Guild.icon`,
:attr:`.Guild.id`, and :attr:`.Guild.name` per :class:`.Guild`.
.. note::
This method is an API call. For general usage, consider :attr:`guilds` instead.
Examples
---------
Usage ::
async for guild in client.fetch_guilds(limit=150):
print(guild.name)
Flattening into a list ::
guilds = await client.fetch_guilds(limit=150).flatten()
# guilds is now a list of Guild...
All parameters are optional.
Parameters
-----------
limit: Optional[:class:`int`]
The number of guilds to retrieve.
If ``None``, it retrieves every guild you have access to. Note, however,
that this would make it a slow operation.
Defaults to 100.
before: Union[:class:`.abc.Snowflake`, :class:`datetime.datetime`]
Retrieves guilds before this date or object.
If a date is provided it must be a timezone-naive datetime representing UTC time.
after: Union[:class:`.abc.Snowflake`, :class:`datetime.datetime`]
Retrieve guilds after this date or object.
If a date is provided it must be a timezone-naive datetime representing UTC time.
Raises
------
:exc:`.HTTPException`
Getting the guilds failed.
Yields
--------
:class:`.Guild`
The guild with the guild data parsed.
