Struct `SyncWaker`

pub(crate) struct SyncWaker { pub(in ::sync::mpmc::waker) inner: Mutex<Waker>, pub(in ::sync::mpmc::waker) is_empty: Atomic<bool> }

A waker that can be shared among threads without locking.

This is a simple wrapper around Waker that internally uses a mutex for synchronization.

Fields

inner: Mutex<Waker>: The inner Waker.
is_empty: Atomic<bool>: true if the waker is empty.

Implementations

`impl SyncWaker`

fn new() -> Self: Creates a new SyncWaker.
fn register(&self, oper: Operation, cx: &Context): Registers the current thread with an operation.
fn unregister(&self, oper: Operation) -> Option<Entry>: Unregisters an operation previously registered by the current thread.
fn notify(&self): Attempts to find one thread (not the current one), select its operation, and wake it up.
fn disconnect(&self): Notifies all threads that the channel is disconnected.
