Hyperbridge

Fast multi-producer, multi-consumer unbounded channel with async support. Inspired by crossbeam unbounded channel.

Examples

Hyperbridge::channel: mpsc

use hyperbridge::channel;
use std::thread;

let (sender, receiver) = hyperbridge::channel::new();
let mut counter = 0;
let threads = 10;
let values = 10000;

let mut handles = vec![];

for i in 0..threads {
    let ch = sender.clone();
    let jh = thread::spawn(move || {
        for _ in 0..values {
            ch.send(i).unwrap();
        }
    });
    handles.push(jh);
}

let mut iters = threads * values;

while iters > 0 {
    match receiver.try_recv() {
        Ok(Some(v)) => {
            counter += v as usize;
            iters -= 1;
        }
        _ => {}
    }
}

let total = (0..threads).map(|i| i * values).sum();

for jh in handles.drain(..) {
    let _ = jh.join();
}

Hyperbridge::channel: mpmc

use hyperbridge::channel;
use std::thread;

const VALUES: usize = 10000;
const THREADS: usize = 16;

let (sender, receiver) = channel::new();
let counter = Arc::new(AtomicUsize::new(0));

let mut handles = vec![];

for i in 0..THREADS {
    let ch = sender.clone();
    let jh = thread::spawn(move || {
        for _ in 0..VALUES {
            ch.send(i).unwrap();
        }
    });
    handles.push(jh);
}

for _ in 0..THREADS {
    let ch = receiver.clone();
    let local_counter = counter.clone();
    let jh = thread::spawn(move || {
        let mut iters = VALUES;
        while iters > 0 {
            if let Ok(Some(v)) = ch.try_recv() {
                local_counter.fetch_add(v as usize, Relaxed);
                iters -= 1;
            }
        }
    });
    handles.push(jh);
}

for jh in handles.drain(..) {
    let _ = jh.join();
}

let total = (0..THREADS).map(|i| i * VALUES).sum();
