pub struct ArcReentrantMutexGuard<R: RawMutex, G: GetThreadId, T: ?Sized> { /* private fields */ }
Available on crate features atomic_usize and arc_lock only.
Expand description

An RAII mutex guard returned by the Arc locking operations on ReentrantMutex.

This is similar to the ReentrantMutexGuard struct, except instead of using a reference to unlock the Mutex it uses an Arc<ReentrantMutex>. This has several advantages, most notably that it has an 'static lifetime.

Implementations§

source§

impl<R: RawMutex, G: GetThreadId, T: ?Sized> ArcReentrantMutexGuard<R, G, T>

source

pub fn remutex(s: &Self) -> &Arc<ReentrantMutex<R, G, T>>

Returns a reference to the ReentrantMutex this object is guarding, contained in its Arc.

source

pub fn unlocked<F, U>(s: &mut Self, f: F) -> Uwhere F: FnOnce() -> U,

Temporarily unlocks the mutex to execute the given function.

This is safe because &mut guarantees that there exist no other references to the data protected by the mutex.

source§

impl<R: RawMutexFair, G: GetThreadId, T: ?Sized> ArcReentrantMutexGuard<R, G, T>

source

pub fn unlock_fair(s: Self)

Unlocks the mutex using a fair unlock protocol.

This is functionally identical to the unlock_fair method on ReentrantMutexGuard.

source

pub fn unlocked_fair<F, U>(s: &mut Self, f: F) -> Uwhere F: FnOnce() -> U,

Temporarily unlocks the mutex to execute the given function.

This is functionally identical to the unlocked_fair method on ReentrantMutexGuard.

source

pub fn bump(s: &mut Self)

Temporarily yields the mutex to a waiting thread if there is one.

This is functionally equivalent to the bump method on ReentrantMutexGuard.
