struct Waiter {
    pointers: Pointers<Waiter>,
    waker: UnsafeCell<Option<Waker>>,
    notification: AtomicNotification,
    _p: PhantomPinned,
}

Fields§

§pointers: Pointers<Waiter>

Intrusive linked-list pointers.

§waker: UnsafeCell<Option<Waker>>

Waiting task’s waker. Depending on the value of notification, this field is either protected by the waiters lock in Notify, or it is exclusively owned by the enclosing Waiter.

§notification: AtomicNotification

Notification for this waiter.

  • if it’s None, then waker is protected by the waiters lock.
  • if it’s Some, then waker is exclusively owned by the enclosing Waiter and can be accessed without locking.
§_p: PhantomPinned

Should not be Unpin.
