Function tokio_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 tokio_stream::{self as stream, StreamExt}; let mut stream = stream::iter(vec![17, 19]); assert_eq!(stream.next().await, Some(17)); assert_eq!(stream.next().await, Some(19)); assert_eq!(stream.next().await, None);
