Function futures_util::stream::iter

pub fn iter<I>(i: I) -> Iter<I::IntoIter>

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 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);
