greenie
Simple green threads in Rust programming language.
Features
- Generators in stable Rust!
- Synchronization primitives:
Mutex
,Condvar
others will be implemented later ( see TODO ). - Fast.
- Semi-automatic scheduling using
greenify
macro that inserts yield points in your functions.
TODO
- Preemptive scheduling.
- Implement
RwLock
. - Futures.
Example
Condvar and Mutex example:
use greenie::channel::*;
use greenie::{greeny_main, Fiber};
#[greeny_main]
fn main() {
let chan_1 = Channel::<&'static str>::new(2);
let chan_2 = Channel::<&'static str>::new(2);
let fping = Fiber::new_capture(
|chan_1, chan_2| {
chan_1.send("ping");
println!("{}", chan_2.recv().unwrap());
chan_1.send("ping");
println!("{}", chan_2.recv().unwrap());
chan_1.send("ping");
println!("{}", chan_2.recv().unwrap());
},
(chan_1.clone(), chan_2.clone()),
);
let fpong = Fiber::new_capture(
|chan_1, chan_2| {
chan_2.send("pong");
println!("{}", chan_1.recv().unwrap());
chan_2.send("pong");
println!("{}", chan_1.recv().unwrap());
chan_2.send("pong");
println!("{}", chan_1.recv().unwrap());
},
(chan_1.clone(), chan_2.clone()),
);
fpong.start().unwrap();
fping.start().unwrap();
}
