Types and Traits for working with asynchronous tasks.

## Macros§

ready
  Extracts the successful type of a `Poll<T>`.

## Structs§

Context
  The context of an asynchronous task.
RawWaker
  A `RawWaker` allows the implementor of a task executor to create a `Waker` or a `LocalWaker` which provides customized wakeup behavior.
RawWakerVTable
  A virtual function pointer table (vtable) that specifies the behavior of a `RawWaker`.
Waker
  A `Waker` is a handle for waking up a task by notifying its executor that it is ready to be run.
ContextBuilderExperimental
  A Builder used to construct a `Context` instance with support for `LocalWaker`.
LocalWakerExperimental
  A `LocalWaker` is analogous to a `Waker`, but it does not implement `Send` or `Sync`.

## Enums§

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

## Traits§

Wake`target_has_atomic=ptr`
  The implementation of waking a task on an executor.
LocalWakeExperimental
  An analogous trait to `Wake` but used to construct a `LocalWaker`.

## Functions§

local_waker_fnExperimental
  Converts a closure into a `LocalWaker`.
waker_fnExperimental`target_has_atomic=ptr`
  Converts a closure into a `Waker`.
