hyperlane-broadcast

Official Documentation

Api Docs

hyperlane-broadcast is a lightweight and ergonomic wrapper over Tokio’s broadcast channel designed for easy-to-use publish-subscribe messaging in async Rust applications. It simplifies the native Tokio broadcast API by providing a straightforward interface for broadcasting messages to multiple subscribers with minimal boilerplate.

Installation

To use this crate, you can run cmd:

cargo add hyperlane-broadcast

Use

use hyperlane_broadcast::*;

let broadcast: Broadcast<usize> = Broadcast::new(10);
let mut rec1: BroadcastReceiver<usize> = broadcast.subscribe();
let mut rec2: BroadcastReceiver<usize> = broadcast.subscribe();
broadcast.send(20).unwrap();
assert_eq!(rec1.recv().await, Ok(20));
assert_eq!(rec2.recv().await, Ok(20));

let broadcast_map: BroadcastMap<usize> = BroadcastMap::new();
broadcast_map.insert("a", 10);
let mut rec1: BroadcastMapReceiver<usize> = broadcast_map.subscribe("a").unwrap();
let mut rec2: BroadcastMapReceiver<usize> = broadcast_map.subscribe("a").unwrap();
let mut rec3: BroadcastMapReceiver<usize> =
    broadcast_map.subscribe_or_insert("b", DEFAULT_BROADCAST_SENDER_CAPACITY);
broadcast_map.send("a", 20).unwrap();
broadcast_map.send("b", 10).unwrap();
assert_eq!(rec1.recv().await, Ok(20));
assert_eq!(rec2.recv().await, Ok(20));
assert_eq!(rec3.recv().await, Ok(10));
