source · Expand description
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.

- spawn 🔒
Structs§
- A synchronization primitive for task wakeup.
- 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>
. - An error that occurred during spawning.
- A
Waker
that is only valid for a given lifetime.
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.
