Struct Notify 

pub struct Notify { /* private fields */ }

Notification primitive for efficient task coordination

Implementations

impl Notify

pub fn new() -> Self

Create a new notification primitive

pub fn notified(&self) -> NotifyFuture<'_>

Wait for a notification

pub fn notify_one(&self)

Notify one waiting task

The waker is taken under the state lock and woken after it is released: Waker::wake may poll the task inline on this thread, and that poll re-locks this state — waking under the lock would self-deadlock. Same discipline as notify_waiters below and hybrid::notify.

pub fn notify_waiters(&self)

Notify all waiting tasks.

Wakes every currently-registered waiter. This is independent of the single-permit notify_one mechanism: a permit stored by a prior notify_one (issued with no waiters present) is left intact, so a subsequent notified() still observes it.

Trait Implementations

impl Default for Notify

fn default() -> Self

Returns the “default value” for a type.
