tokio-bus

Integration to let you use bus with tokio.

Deprecated

The functionality here (forwarding messages such that all consumers receive it) has been put in to tokio itself in the tokio::sync::broadcast module.

Example

use tokio;
use tokio_bus::Bus;
use futures::future::{Future, lazy, ok};
use futures::stream::{Stream, iter_ok};
use futures::sink::Sink;

let mut bus = Bus::new(64);
let rx1 = bus.add_rx();
let rx2 = bus.add_rx();

let send_values = bus
    .send_all(iter_ok::<_, ()>(vec![1, 2, 3, 4, 5, 6]));

let sum_values = rx1
    .fold(0i32, |acc, x| { ok(acc + x) });

let div_values = rx2
    .fold(1f64, |acc, x| { ok(x as f64 / acc) });

let runtime = tokio::runtime::Runtime::new().unwrap();
runtime.block_on_all(lazy(move || {
    tokio::spawn(send_values
        .map(|_| {})
        .map_err(|_| { panic!(); })
    );
    assert_eq!(sum_values.wait(), Ok(21));
    assert_eq!(div_values.wait(), Ok(3.2));
    ok::<(), ()>(())
})).unwrap();
