Enum EventHandler 

pub enum EventHandler {
    None,
    Enqueue {
        key: ReadyItemKey,
        queue: Arc<Mutex<VecDeque<ReadyItem>>>,
        sought_events: FdEvents,
    },
    HandleOnce(Arc<Mutex<Option<EventHandler>>>),
    Epoll(EpollEventHandler),
}

Variants

None

Does nothing.

It is up to the waiter to synchronize itself with the notifier if synchronization is needed.

Enqueue

Enqueues an event to a ready list.

This event handler naturally synchronizes the notifier and notifee because of the lock acquired/released when enqueuing the event.

Fields

key: ReadyItemKey

queue: Arc<Mutex<VecDeque<ReadyItem>>>

sought_events: FdEvents

HandleOnce(Arc<Mutex<Option<EventHandler>>>)

Wraps another EventHandler and only triggers it once. Further .handle() calls are ignored.

This is intended for cases like BinderFileObject which need to register the same EventHandler on multiple wait queues.

Epoll(EpollEventHandler)

This handler is an epoll.
