Generator-rs

rust stackful generator library

[dependencies]
generator = "0.8"

Usage

use generator::{done, Gn};

fn main() {
    let g = Gn::new_scoped(|mut s| {
        let (mut a, mut b) = (0, 1);
        while b < 200 {
            std::mem::swap(&mut a, &mut b);
            b = a + b;
            s.yield_(b);
        }
        done!();
    });

    for i in g {
        println!("{}", i);
    }
}

Goals

  • basic send/yield with message support
  • generator cancel support
  • yield_from support
  • panic inside generator support
  • stack size tune support
  • scoped static type support
  • basic coroutine interface support
  • stable rust support

based on this basic library

  • we can easily port python library based on generator into rust
  • coroutine framework running on multi thread
