ReadyObservable

async_foundation::common::ready_observable

Struct ReadyObservable

pub struct ReadyObservable { /* private fields */ }

Expand description

A simple observable that lets multiple waiters be notified when an event occurs.

ReadyObservable starts in a non-ready state; callers can obtain a ReadyFuture<()> via ReadyObservable::wait. When ReadyObservable::complete is called, all pending waiters are woken and subsequent calls to wait return an already-completed future.

Implementations§

impl ReadyObservable

pub fn complete(&mut self)

pub fn is_ready(&self) -> bool

pub fn wait(&mut self) -> ReadyFuture<()> ⓘ
