A RefCell for sharing data with interrupt handlers or signal handlers on the same thread.

use interrupt_ref_cell::{InterruptRefCell, LocalKeyExt};
 
thread_local! {
    static X: InterruptRefCell<Vec<i32>> = InterruptRefCell::new(Vec::new());
}
 
fn interrupt_handler() {
    X.with_borrow_mut(|v| v.push(1));
}

X.with_borrow(|v| {
    // Raise an interrupt
    raise_interrupt();
    assert_eq!(*v, vec![]);
});
 
// The interrupt handler runs
 
X.with_borrow(|v| assert_eq!(*v, vec![1]));
