wag ="0.3.0"

How to use,

use wag::WaitGroup;let wg =WaitGroup::new();

for _in0..10{let w = wg.add();    thread::spawn(move ||{// ...        w.done();});});wg.wait();// or wg.async_wait().await;

for win wg.adds::<10>(){    thread::spawn(move ||{// ...        w.done();});});wg.wait();// or wg.async_wait().await;

let[w1, w2, w3] = wg.adds();thread::spawn(move ||{// ...    w1.done();});thread::spawn(move ||{// ...    w2.done();});thread::spawn(move ||{// ...    w3.done();});wg.wait();// or wg.async_wait().await;

wg.adds_iter::<10>().enumerate().for_each(|(i, w)|{    thread::spawn(move ||{// ... with i        w.done();});});wg.wait();// or wg.async_wait().await;
