Function spawn 

pub fn spawn<F>(future: F) -> JoinHandle<<F as Future>::Output> 
where
    F: Future + 'static,

Available on crate feature runtime only.

Spawns a new asynchronous task, returning a JoinHandle for it.

Spawning a task enables the task to execute concurrently to other tasks. There is no guarantee that a spawned task will execute to completion.

use compio_runtime::ResumeUnwind;

let task = compio_runtime::spawn(async {
    println!("Hello from a spawned task!");
    42
});

assert_eq!(
    task.await.resume_unwind().expect("shouldn't be cancelled"),
    42
);

Panics

This method doesn’t create runtime. It tries to obtain the current runtime by Runtime::with_current.
