create managed sub coroutines. managed sub coroutines will be cancelled when the parent exit this is some like the scoped coroutine creation, the difference is that we manage the sub coroutines in a hash map, so that when sub coroutine exit the entry will be removed dynamically and parent doesn’t wait it’s children exit

§co_managed

This lib could create managed sub coroutines.

Managed sub coroutines will be cancelled when their parent exit. This is something like the scoped coroutine creation, the difference is that we manage the sub coroutines in a hash map, so that when sub coroutine exit the entry will be removed dynamically and parent doesn’t wait it’s children exit.

§Usage

First, add this to your Cargo.toml:

[dependencies]
co_managed = "0.1"

Then just simply implement your http service

use may::{go, coroutine};
use co_managed::Manager;
use std::time::Duration;
fn main() {
    let j = go!(|| {
        println!("parent started");
        let manager = Manager::new();
        struct Dummy(usize);
        impl Drop for Dummy {
            fn drop(&mut self) {
                println!("co dropped, id={}", self.0);
            }
        }
        for i in 0..10 {
            manager.add(move || {
                let d = Dummy(i);
                println!("sub started, id = {}", d.0);
                loop {
                    coroutine::sleep(Duration::from_millis(10));
                }
            });
        }
        coroutine::park();
    });

    coroutine::sleep(Duration::from_millis(100));
    unsafe { j.coroutine().cancel() };
    j.join().ok();
    println!("parent exit");
    coroutine::sleep(Duration::from_millis(1000));
}
