Struct SpinLocked

Source 
pub struct SpinLocked<T> { /* private fields */ }
Expand description

A mutual exclusion primitive that allows at most one thread to access a resource at a time.

Implementations§

Source§

impl<T> SpinLocked<T>

Test

Source

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

Creates a new SpinLocked.

Source

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

Locks the SpinLocked and returns a guard that releases the lock when dropped.

Source

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

Tries to lock the SpinLocked and returns a guard that releases the lock when dropped.
