"""Asynchronous access to MPD using the asyncio methods of Python 3.
|
||||
|
||||
Interaction happens over the mpd.asyncio.MPDClient class, whose connect and
|
||||
command methods are coroutines.
|
||||
|
||||
Some commands (eg. listall) additionally support the asynchronous iteration
|
||||
(aiter, `async for`) interface; using it allows the library user to obtain
|
||||
items of result as soon as they arrive.
|
||||
|
||||
The .idle() method works differently here: It is an asynchronous iterator that
|
||||
produces a list of changed subsystems whenever a new one is available. The
|
||||
MPDClient object automatically switches in and out of idle mode depending on
|
||||
which subsystems there is currently interest in.
|
||||
|
||||
Command lists are currently not supported.
|
||||
|
||||
|
||||
This module requires Python 3.5.2 or later to run.
