pub trait Merge {
type Item;
type Stream: Stream<Item = Self::Item>;
// Required method
fn merge(self) -> Self::Stream;
}Expand description
Combines multiple streams into a single stream of all their outputs.
Items are yielded as soon as they’re received, and the stream continues yield until both streams have been exhausted. The output ordering between streams is not guaranteed.
§Examples
use futures_concurrency::prelude::*;
use futures_lite::stream::{self, StreamExt};
use futures_lite::future::block_on;
block_on(async {
let a = stream::once(1);
let b = stream::once(2);
let c = stream::once(3);
let mut s = [a, b, c].merge();
let mut buf = vec![];
s.for_each(|n| buf.push(n)).await;
buf.sort_unstable();
assert_eq!(&buf, &[1, 2, 3]);
})
