Crate pflock

This library provides a phase-fair reader-writer lock, as described in the paper "Reader-Writer Synchronization for Shared-Memory Multiprocessor Real-Time Systems" by Brandenburg et. al.

Example

use pflock::PFLock;

let lock = PFLock::new(5);

// many reader locks can be held at once
{
    let r1 = lock.read();
    let r2 = lock.read();
    assert_eq!(*r1, 5);
    assert_eq!(*r2, 5);
} // read locks are dropped at this point

// only one write lock may be held, however
{
    let mut w = lock.write();
    *w += 1;
    assert_eq!(*w, 6);
} // write lock is dropped here
