[][src]Crate futures_task

Tools for working with tasks.

Structs

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.

Spawn

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

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>.
