Crate generic_channel

Generic-channel provides common abstract traits Sender, Receiver between several channel implementations that widely used in the Rust community.

Currently support channel implementations:

• std
• crossbeam-channel
• futures

NOTE: you need to enable those features in Cargo.toml, use all flag to enable all.

A handler function only wants to handle a sender or receiver to send/recv messages and do not care about the actual type or whether the sender is a crossbeam sender or a futures sender.

Examples

use generic_channel::{Sender, TrySendError};

// this method do not care about sender type.
fn event_producer<S: Sender<i32>>(sender: S) -> Result<(), TrySendError<i32>> {
    for i in 1..10 {
        sender.try_send(i)?
    }
    Ok(())
}

// we can pass crossbeam channel to event_producer
let (sender, receiver) = crossbeam_channel::unbounded::<i32>();
event_producer(sender);
assert_eq!((1..10).map(|_| receiver.recv().unwrap()).collect::<Vec<_>>(), (1..10).collect::<Vec<_>>());

// we can also pass a std Sender or a futures Sender
let (sender, receiver) = std::sync::mpsc::channel::<i32>();
event_producer(sender);
assert_eq!((1..10).map(|_| receiver.recv().unwrap()).collect::<Vec<_>>(), (1..10).collect::<Vec<_>>());
