1 | //! Tools for working with tasks. |
2 | //! |
3 | //! This module contains: |
4 | //! |
5 | //! - [`Spawn`], a trait for spawning new tasks. |
6 | //! - [`Context`], a context of an asynchronous task, |
7 | //! including a handle for waking up the task. |
8 | //! - [`Waker`], a handle for waking up a task. |
9 | //! |
10 | //! The remaining types and traits in the module are used for implementing |
11 | //! executors or dealing with synchronization issues around task wakeup. |
