//! Composable asynchronous iteration.
//!
//! This module is an async version of [`std::iter`].
//!
//! [`std::iter`]: https://doc.rust-lang.org/std/iter/index.html
//!
//! # Examples
//!
//! ```
//! # async_std::task::block_on(async {
//! #
//! use async_std::prelude::*;
//! use async_std::stream;
//!
//! let mut s = stream::repeat(9).take(3);
//!
//! while let Some(v) = s.next().await {
//!     assert_eq!(v, 9);
//! }
//! #
//! # })
//! ```
