[][src]Module heim_common::prelude::futures::task

Task notification

Structs

AtomicWaker

A synchronization primitive for task wakeup.

Context

The Context of an asynchronous task.

FutureObj

A custom trait object for polling futures, roughly akin to Box<dyn Future<Output = T> + Send + 'a>.

LocalFutureObj

A custom trait object for polling futures, roughly akin to Box<dyn Future<Output = T> + 'a>.

RawWaker

A RawWaker allows the implementor of a task executor to create a Waker which provides customized wakeup behavior.

RawWakerVTable

A virtual function pointer table (vtable) that specifies the behavior of a RawWaker.

SpawnError

An error that occurred during spawning.

Waker

A Waker is a handle for waking up a task by notifying its executor that it is ready to be run.

WakerRef

A Waker that is only valid for a given lifetime.

Enums

Poll

Indicates whether a value is available or if the current task has been scheduled to receive a wakeup instead.

Traits

ArcWake

A way of waking up a specific task.

LocalSpawn

The LocalSpawn is similar to Spawn, but allows spawning futures that don't implement Send.

LocalSpawnExt

Extension trait for LocalSpawn.

Spawn

The Spawn trait allows for pushing futures onto an executor that will run them to completion.

SpawnExt

Extension trait for Spawn.

UnsafeFutureObj

A custom implementation of a future trait object for FutureObj, providing a vtable with drop support.

Functions

noop_waker

Create a new Waker which does nothing when wake() is called on it.

noop_waker_ref

Get a static reference to a Waker which does nothing when wake() is called on it.

waker

Creates a Waker from an Arc<impl ArcWake>.

waker_ref

Creates a reference to a Waker from a reference to Arc<impl ArcWake>.
