Struct lock_api::ArcMutexGuard
source · pub struct ArcMutexGuard<R: RawMutex, T: ?Sized> { /* private fields */ }
Expand description
An RAII mutex guard returned by the Arc
locking operations on Mutex
.
This is similar to the MutexGuard
struct, except instead of using a reference to unlock the Mutex
it
uses an Arc<Mutex>
. This has several advantages, most notably that it has an 'static
lifetime.

sourcepub fn unlock_fair(s: Self)
pub fn unlock_fair(s: Self)
Unlocks the mutex using a fair unlock protocol.
This is functionally identical to the unlock_fair
method on MutexGuard
.
sourcepub fn unlocked_fair<F, U>(s: &mut Self, f: F) -> Uwhere
F: FnOnce() -> U,
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 MutexGuard
.
sourcepub fn bump(s: &mut Self)
pub fn bump(s: &mut Self)
Temporarily yields the mutex to a waiting thread if there is one.
This is functionally identical to the bump
method on MutexGuard
.
