futures_ext
An extension of futures
.
Document
For now, this crate provides
- unsync unbounded publish subscribe channel
- unsync unbounded cloneable stream
And will provide in future
- unsync bounded publish subscribe channel
- sync unbounded publish subscribe channel
- sync bounded publish subscribe channel
- unsync bounded cloneable stream
- sync unbounded cloneable stream
- sync bounded cloneable stream
How to use
Publish-Subscribe channel
An usage is almost same with futures::unsync::mpsc::unbounded
.
use ex_futures::unsync::pubsub::unbounded;
fn main() {
let (tx, rx) = unbounded::<usize>();
let rx2 = rx.clone();
let mut rx = rx.wait();
let mut rx2 = rx.wait();
tx.send(1).wait().unwrap();
assert_eq!(rx.next().unwrap().map(|i| *i), Ok(1));
assert_eq!(rx2.next().unwrap().map(|i| *i), Ok(1));
}
Cloneable stream
use ex_futures::StreamExt;
fn main() {
let stream = gen_inc_stream();;
let cloneable = stream.unsync_cloneable();
let cloneable2 = cloneable.clone();
assert_eq!(cloneable.map(|i| *i).collect().wait().unwrap(), [0, 1, 2, 3]);
assert_eq!(cloneable2.map(|i| *i).collect().wait().unwrap(), [0, 1, 2, 3]);
}
