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.
