README

        
This is a tool for managing asynchronous tasks.

For example, maybe you have some periodic background tasks, plus a couple web servers. Using a `TaskManager` you can group these and shut them down as a group, gracefully, and wait for them all to end.

Handles

- Long tasks

- Simple periodic tasks (fixed sleep between invocations)

- Async streams

- Ctrl+c shutdown

Use it like

```rust

let tm = TaskManager::new();

tm.attach_sigint({

    log2 = logger.clone();

    |e| log2.err("Error handling sigint", e)

});

let tm1 = tm.clone();

let log2 = logger.clone();

tm.task(async move {

    match tm1.if_alive(server).await {

        Some(r) => match r {

            Ok(_) => {} // Server exited normally

            Err(e) => {

                log.err("Server died with error", e);

            }

        },

        None => {} // Received shutdown

    };

});

tm.join().await;

```
