dark-std

dark-std is an Implementation of asynchronous

• defer! (defer macro)
• SyncHashMap (async HashMap)
• SyncBtreeMap (async BtreeMap)
• SyncVec (async Vec)
• WaitGroup (async/blocking all support WaitGroup)

for example: ```rust #[tokio::test] pub async fn test_get() { let m = SyncHashMap::::new(); let insert = m.insert(1, 2);

    let g = m.get(&1).unwrap();//don't need lock and await
    assert_eq!(&2, g);
}

```

wait group: ```rust use std::time::Duration; use tokio::time::sleep; use dark_std::sync::WaitGroup;

[tokio::test]

async fn testwg() { let wg = WaitGroup::new(); let wg2 = wg.clone(); tokio::spawn(async move { sleep(Duration::fromsecs(1)).await; drop(wg2); }); let wg2 = wg.clone(); tokio::spawn(async move { sleep(Duration::fromsecs(1)).await; drop(wg2); }); wg.waitasync().await; println!("all done"); } ```
