示例

使用add & done

use taskwait::TaskGroup;
 
let tg = TaskGroup::();
for _ in 0..10 {
    tg.add();
    let tg_c = tg.clone();
    tokio::spawn(async move{
        ...
        tg_c.done();
    })
}
tg.wait().await;

使用add & add_work

use taskwait::TaskGroup;
 
let tg = TaskGroup::();
for _ in 0..10 {
    let work = tg.add_work(1); // Increment counter
    tokio::spawn(async move{
        let _work = work; // done() will be called when this is dropped
        ...
    })
}
tg.wait().await;
