> ## v1.3.0
> 
> [API Documentation](https://docs.rs/async-std/1.3.0/async-std)
> 
> This patch introduces `Stream::delay`, more methods on `DoubleEndedStream`,
> and improves compile times. `Stream::delay` is a new API that's similar to
> [`task::sleep`](https://docs.rs/async-std/1.2.0/async_std/task/fn.sleep.html),
> but can be passed as part of as stream, rather than as a separate block. This is
> useful for examples, or when manually debugging race conditions.
> 
> ## Examples
> 
> ```rust
> let start = Instant::now();
> let mut s = stream::from_iter(vec![0u8, 1]).delay(Duration::from_millis(200));
> 
> // The first time will take more than 200ms due to delay.
> s.next().await;
> assert!(start.elapsed().as_millis() >= 200);
> 
> // There will be no delay after the first time.
> s.next().await;
> assert!(start.elapsed().as_millis() <= 210);
> ```
