Struct ostd :: sync :: SpinLock Copy item path

impl<T> SpinLock<T>

pub const fn new(val: T) -> Self

Creates a new spin lock.

impl<T: ?Sized> SpinLock<T>

pub fn lock_irq_disabled(&self) -> SpinLockGuard<'_, T>

Acquires the spin lock with disabling the local IRQs. This is the most secure locking way.

This method runs in a busy loop until the lock can be acquired. After acquiring the spin lock, all interrupts are disabled.

pub fn try_lock_irq_disabled(&self) -> Option<SpinLockGuard<'_, T>>

Tries acquiring the spin lock immedidately with disabling the local IRQs.

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

Acquires the spin lock without disabling local IRQs.

This method is twice as fast as the lock_irq_disabled method. So prefer using this method over the lock_irq_disabled method when IRQ handlers are allowed to get executed while holding this lock. For example, if a lock is never used in the interrupt context, then it is ok to use this method in the process context.

pub fn lock_arc(self: &Arc<Self>) -> ArcSpinLockGuard<T>

Acquires the spin lock through an [Arc].

The method is similar to lock, but it doesn’t have the requirement for compile-time checked lifetimes of the lock guard.

pub fn try_lock(&self) -> Option<SpinLockGuard<'_, T>>

Tries acquiring the spin lock immedidately without disabling the local IRQs.
