Struct SpinLock 

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

A simple spin lock.

The lock is acquired via a compare-exchange loop and released on guard drop.

§Safety

This type is Send/Sync when T: Send and relies on correct atomic behavior. As with any spin lock, make sure lock hold times are short.

Implementations§

Source§

impl<T> SpinLock<T>

Source

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

Creates a new spin lock protecting value.

Source

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

Acquires the lock and returns a guard.

This spins until the lock becomes available.
