//!
//! Helpers for fusing asynchronous computations.
//!
//! This is especially useful in combination with optional branches using
//! [tokio::select], where the future being polled isn't necessarily set. So
//! instead of requiring a potentially problematic [branch precondition], the
//! future will simply be marked as pending indefinitely.
//!
//! # Features
//!
//! * `stream` - Makes `Heap` and `Stack` implement the [`Stream` trait] if
//!   they contain a stream.
//!
//! # Examples
//!
//! > This is available as the `ticker` example:
//! > ```sh
//! > cargo run --example ticker
//! > ```
//!
//! ```rust
//! use std::time::Duration;
//! use tokio::time;
//!
//! # #[tokio::main]
//! # async fn main() {
//! let sleep = async_fuse::Stack::new(time::sleep(Duration::from_millis(100)));
//! tokio::pin!(sleep);
//!
//! for _ in 0..20usize {
//!     (&mut sleep).await;
//!     assert!(sleep.is_empty());
//!
//!     println!("tick");
//!
//!     sleep.set(async_fuse::Stack::new(time::sleep(Duration::from_millis(100))))
//! }
//! # }
//! ```
