Struct lib_wc::sync::SpinLock

pub struct SpinLock<T> { /* private fields */ }

a primitive for mutual exclusion that spins in a loop

Implementations

impl<T> SpinLock<T>

pub fn new(value: T) -> Self

Creates a new spinlock.

Examples

  use lib_wc::sync::SpinLock;

  let spinlock = SpinLock::new(0);

  {
    let mut guard = spinlock.lock();
    *guard += 1;
  } // The guard is dropped here, unlocking the mutex

  {
    let mut guard = spinlock.lock();
    *guard += 1;
  } // The guard is dropped here, unlocking the mutex

  assert_eq!(*spinlock.lock(), 2);

pub fn lock(&self) -> Guard<'_, T>

Acquires a lock on the spinlock, spinning the current thread in a loop until it is able to do so.

This function returns a Guard which will release the lock when dropped.

Examples

  use lib_wc::sync::SpinLock;

  let spinlock = SpinLock::new(0);

  {
    let mut guard = spinlock.lock();
    *guard += 1;
  } // The guard is dropped here, unlocking the mutex

  {
    let mut guard = spinlock.lock();
    *guard += 1;
  } // The guard is dropped here, unlocking the mutex

  assert_eq!(*spinlock.lock(), 2);
