Waker

Struct Waker

pub struct Waker { /* private fields */ }

Expand description

A waker that can wake up the associated Waiter.

A waker can be created by calling Waiter::new_pair. This method creates an Arc<Waker> that can be used across different threads.

Implementations§

impl Waker

pub closed spec fn id(self) -> int

Abstract identity used by the queue model.

impl Waker

pub exec fn wake_up(&self) -> bool

Wakes up the associated Waiter.

This method returns true if the waiter is woken by this call. It returns false if the waiter has already been woken by a previous call to the method, or if the waiter has been dropped.

Note that if this method returns true, it implies that the wake event will be properly delivered, or that the waiter will be dropped after being woken. It’s up to the caller to handle the latter case properly to avoid missing the wake event.
