Crate global

Type-level safe mutable global access, with support for recursive immutable locking.

use global::Global;

// The global value.
static VALUE: Global<i32> = Global::INIT;

// Spawn 100 threads and join them all.
let mut threads = Vec::new();

for _ in 0..100 {
    threads.push(std::thread::spawn(|| {
        *VALUE.lock_mut().unwrap() += 1;
    }));
}

for thread in threads {
    thread.join().unwrap();
}

// This value is guaranteed to be 100.
assert_eq!(*VALUE.lock().unwrap(), 100);
