Chip-Generic Interrupt Utilities

For the most part, crate::interrupt::free is what you want:

avr_device::interrupt::free(|cs| {
    // Interrupts are disabled here
});

To access shared state, Mutex can be used:

use avr_device::interrupt::Mutex;
use core::cell::Cell;

// Use Cell, if the wrapped type is Copy.
// Use RefCell, if the wrapped type is not Copy or if you need a reference to it for other reasons.
static MYGLOBAL: Mutex<Cell<u16>> = Mutex::new(Cell::new(0));

avr_device::interrupt::free(|cs| {
    // Interrupts are disabled here

    // Acquire mutex to global variable.
    let myglobal_ref = MYGLOBAL.borrow(&cs);
    // Write to the global variable.
    myglobal_ref.set(42);
});
