Tools for working with tasks.
This module contains:
Spawn, a trait for spawning new tasks.Context, a context of an asynchronous task, including a handle for waking up the task.Waker, a handle for waking up a task.
The remaining types and traits in the module are used for implementing executors or dealing with synchronization issues around task wakeup.
Structs
A synchronization primitive for task wakeup.
The context of an asynchronous task.
A custom trait object for polling futures, roughly akin to
Box<dyn Future<Output = T> + Send + 'a>.A custom trait object for polling futures, roughly akin to
Box<dyn Future<Output = T> + 'a>.A
RawWaker allows the implementor of a task executor to create a Waker
which provides customized wakeup behavior.A virtual function pointer table (vtable) that specifies the behavior
of a
RawWaker.An error that occurred during spawning.
A
Waker is a handle for waking up a task by notifying its executor that it
is ready to be run.Enums
Indicates whether a value is available or if the current task has been
scheduled to receive a wakeup instead.
Traits
A way of waking up a specific task.
Extension trait for
LocalSpawn.The
Spawn trait allows for pushing futures onto an executor that will
run them to completion.Extension trait for
Spawn.A custom implementation of a future trait object for
FutureObj, providing
a vtable with drop support.
