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.
# extern crate generic_channel;
# extern crate crossbeam_channel;
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<_>>());
