[][src]Function futures::stream::repeat

pub fn repeat<T, E>(item: T) -> Repeat<T, E> where
    T: Clone

Create a stream which produces the same item repeatedly.

Stream never produces an error or EOF. Note that you likely want to avoid usage of collect or such on the returned stream as it will exhaust available memory as it tries to just fill up all RAM.

use futures::*;

let mut stream = stream::repeat::<_, bool>(10);
assert_eq!(Ok(Async::Ready(Some(10))), stream.poll());
assert_eq!(Ok(Async::Ready(Some(10))), stream.poll());
assert_eq!(Ok(Async::Ready(Some(10))), stream.poll());
