merge-streams

Merge multiple streams into one.

Based on Yoshua Wuyts's futures-concurrency crate and the corresponding Futures Concurrency III post. Since the futures-concurrency crate now supports stable Rust too, there is no reason to this crate instead anymore.

Example

Merge multiple streams to handle values as soon as they're ready, without ever dropping a single value:

use merge_streams::MergeStreams;
use futures_lite::future::block_on;
use futures_lite::{stream, StreamExt};
fn main() {
    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 counter = 0;
        s.for_each(|n| counter += n).await;
        assert_eq!(counter, 6);
    })
}
