Expand description

Converts an Iterator into a Stream which is always ready to yield the next value.

Iterators in Rust don’t express the ability to block, so this adapter simply always calls iter.next() and returns that.

use futures::stream::{self, StreamExt};

let stream = stream::iter(vec![17, 19]);
assert_eq!(vec![17, 19], stream.collect::<Vec<i32>>().await);
