//! Asynchronous values.
//!
//! This module contains:
//!
//! - The [`Future`] trait.
//! - The [`FutureExt`] and [`TryFutureExt`] trait, which provides adapters for
//! chaining and composing futures.
//! - Top-level future combinators like [`lazy`](lazy()) which creates a future
//! from a closure that defines its return value, and [`ready`](ready()),
//! which constructs a future with an immediate defined value.
