safe-async-scoped is a minimal wrapper around FuturesUnordered in the futures crate that simulates scoped tasks. Unlike async-scoped and even crossbeam-scoped etc, safe-async-scoped

Is completely safe to use
Has no unsafe code in its implementation
Has no dependencies other than futures
Is completely runtime-agnostic

Note that "tasks" spawned with safe-async-scoped will not be sent to the executor as separate tasks, and will thus only run on one thread. On the plus side, none of the futures have to be Send.

Example

let listener = Async::new(TcpListener::bind("127.0.0.1:8080").unwrap()).unwrap();
let lala = String::from("hello");
{
   let scope = Scope::new();
   scope
       .start(async {
           loop {
               let (client, _) = listener.accept().await.unwrap();
               scope.spawn(async {
                   handle(client, &lala).await;
               });
           }
       })
       .await;
}
