Struct RawMutex 

pub struct RawMutex { /* private fields */ }

A non-recursive, urgency-ordered PI mutex implementing lock_api::RawMutex.

The uncontended path uses a Linux rtmutex-style atomic owner word. Its high bit forces contenders through the metadata lock while waiter publication, donation registration, and handoff are in progress. Blocking and targeted wake happen after that metadata guard has been released.

Implementations

impl RawMutex

pub const fn new() -> RawMutex

Creates an unlocked PI mutex.

pub fn is_owned_by_current(&self) -> bool

Returns whether the current thread owns this mutex.

Trait Implementations

impl Default for RawMutex

fn default() -> RawMutex

Returns the “default value” for a type.

impl RawMutex for RawMutex

const INIT: RawMutex

Initial value for an unlocked mutex.

type GuardMarker = GuardNoSend

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

fn lock(&self)

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

fn try_lock(&self) -> bool

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

unsafe fn unlock(&self)

Unlocks this mutex.

fn is_locked(&self) -> bool

Checks whether the mutex is currently locked.
