A mutex for sharing data with interrupt handlers or signal handlers.

// Make a mutex of your choice into an `InterruptMutex`.
type InterruptMutex<T> = interrupt_mutex::InterruptMutex<parking_lot::RawMutex, T>;

static X: InterruptMutex<Vec<i32>> = InterruptMutex::new(Vec::new());

fn interrupt_handler() {
    X.lock().push(1);
}

let v = X.lock();
// Raise an interrupt
raise_interrupt();
assert_eq!(*v, vec![]);
drop(v);

// The interrupt handler runs

let v = X.lock();
assert_eq!(*v, vec![1]);
drop(v);
