+//! Asynchronous streams.
+//!
+//! This module contains:
+//!
+//! - The [`Stream`] trait, for objects that can asynchronously produce a
+//!   sequence of values.
+//! - The [`StreamExt`] and [`TryStreamExt`] trait, which provides adapters for
+//!   chaining and composing streams.
+//! - Top-level stream constructors like [`iter`](iter()) which creates a
+//!   stream from an iterator.
