pub struct RawSpin { /* private fields */ }

A very simple spin-lock.

Consists of a single atomic boolean that is set to true when the lock is acquired and false when it is released. Locks are not fair and not ordered.

Trait Implementations

impl RawMutex for RawSpin

const INIT: Self

Initial value for an unlocked mutex.

type GuardMarker = GuardSend

Marker type which determines whether a lock guard should be Send. Use one of the GuardSend or GuardNoSend helper types here.

fn is_locked(&self) -> bool

Checks whether the mutex is currently locked.

fn try_lock(&self) -> bool

Attempts to acquire this mutex without blocking. Returns true if the lock was successfully acquired and false otherwise.

fn lock(&self)

Acquires this mutex, blocking the current thread until it is able to do so.

unsafe fn unlock(&self)

Unlocks this mutex.
