Struct Notify 

pub struct Notify { /* private fields */ }

A notification primitive commonly used to hand-wake another async task/structure — e.g. signaling “state changed, go re-check” without a full channel.

Implementations

impl Notify

pub const fn new() -> Self

Create a Notify with no stored permit and no waiters.

pub fn notify_one(&self)

Wake one waiting notified().await, or — if none is currently waiting — store a permit so the next notified().await returns immediately without waiting at all.

pub fn notify_waiters(&self)

Wake every task currently waiting in notified().await. Does not store a permit — a task that calls notified() after this returns will wait for a future notification, not this one.

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

A future that resolves once this Notify is notified — either a stored permit is consumed immediately, or a future notify_one/notify_waiters wakes it.

Trait Implementations

impl Default for Notify

fn default() -> Self

Returns the “default value” for a type.
