taskwait

Runtime agnostic way of waiting for async tasks.

Features

• Done: Support for golang's WaitGroup.Add & WaitGroup.Done
• Done: Support for RAII based done()ing the task i.e. calling done() on drop.
• Done: Mixing of both add, done and RAII semantics.
• Todo: Reuse the same taskgroup for multiple checkpoints.

Example

Using add & done

```rust use taskwait::TaskGroup;

let tg = TaskGroup::(); for _ in 0..10 { tg.add(1); let tgc = tg.clone(); tokio::spawn(async move{ ... tgc.done(); }) } tg.wait().await; ```

Using add & auto_work

```rust 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; ```
