Synchronization primitives

==========================
|
||||
|
||||
Locks:
|
||||
|
||||
* :class:`Lock`
|
||||
* :class:`Event`
|
||||
* :class:`Condition`
|
||||
* :class:`Semaphore`
|
||||
* :class:`BoundedSemaphore`
|
||||
|
||||
Queues:
|
||||
|
||||
* :class:`Queue`
|
||||
* :class:`PriorityQueue`
|
||||
* :class:`LifoQueue`
|
||||
* :class:`JoinableQueue`
|
||||
|
||||
asyncio locks and queues API were designed to be close to classes of the
|
||||
:mod:`threading` module (:class:`~threading.Lock`, :class:`~threading.Event`,
|
||||
:class:`~threading.Condition`, :class:`~threading.Semaphore`,
|
||||
:class:`~threading.BoundedSemaphore`) and the :mod:`queue` module
|
||||
(:class:`~queue.Queue`, :class:`~queue.PriorityQueue`,
|
||||
:class:`~queue.LifoQueue`), but they have no *timeout* parameter. The
|
||||
:func:`asyncio.wait_for` function can be used to cancel a task after a timeout.
