Function juggle::spin_block_on

pub fn spin_block_on<F>(future: F) -> F::Output where
    F: Future, 

Utility for busy blocking on future.

Usefull for creating main loop on embedded systems. This function simply polls given future until it is ready. Waker used in polling is no-op, when future yields then it is polled again (with spin_loop_hint optimization).

Equivalent to block_on(future, || spin_loop_hint(), &noop_waker()).

Examples

use juggle::*;

let result = spin_block_on(async move {
    Yield::times(10).await;
    10
});
assert_eq!(result,10);

use juggle::*;

let wheel = Wheel::new();
wheel.handle().spawn(SpawnParams::default(),async move {
    loop{
        do_some_processing();
        yield_once!();
    }
});
wheel.handle().spawn(SpawnParams::default(),async move {
    // some other processing tasks
});

spin_block_on(wheel).unwrap();
