[−][src]Module futures::task

Tools for working with tasks.

This module contains:

The remaining types and traits in the module are used for implementing executors or dealing with synchronization issues around task wakeup.

Structs

AtomicWaker	A synchronization primitive for task wakeup.
RawWaker	Experimental A `RawWaker` allows the implementor of a task executor to create a `Waker` which provides customized wakeup behavior.
RawWakerVTable	Experimental A virtual function pointer table (vtable) that specifies the behavior of a `RawWaker`.
SpawnError	An error that occurred during spawning.
Waker	Experimental 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.

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

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`.

noop_waker	Create a new `Waker` which does nothing when `wake()` is called on it. The `Waker` can be converted into a `Waker` which will behave the same way.
noop_waker_ref	Get a thread local reference to a `Waker` referencing a singleton instance of a `Waker` which panics when woken.
waker_ref	Creates a reference to a `Waker` from a local `wake`.
