//! 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.
