darkrpc/dark-std

an Implementation of asynchronous containers build on tokio. It uses a read-write separation design borrowed from Golang

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)
• AtomicDuration (atomic duration)

for example:

    #[tokio::test]
    pub async fn test_get() {
        let m = SyncHashMap::<i32, i32>::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:

use std::time::Duration;
use tokio::time::sleep;
use dark_std::sync::WaitGroup;
#[tokio::test]
async fn test_wg() {
    let wg = WaitGroup::new();
    let wg2 = wg.clone();
    tokio::spawn(async move {
        sleep(Duration::from_secs(1)).await;
        drop(wg2);
    });
    let wg2 = wg.clone();
    tokio::spawn(async move {
        sleep(Duration::from_secs(1)).await;
        drop(wg2);
    });
    wg.wait_async().await;
    println!("all done");
}
