# Function futures_util::stream::iter [−] [src]

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

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);
