Struct kernel::sync::NoWaitLockGuard

source · [−]

pub struct NoWaitLockGuard<'a, T: ?Sized> { /* private fields */ }

Expand description

A guard for the holder of the no-wait lock.

Invariants

Only the current owner can have an instance of NoWaitLockGuard.

Implementations

source

impl<T: ?Sized> NoWaitLockGuard<'_, T>

source

pub fn unlock(self) -> bool

Unlocks the no-wait lock.

The return value indicates whether there was contention while the lock was held, that is, whether another thread tried (and failed) to acquire the lock.

Trait Implementations

source

impl<T: ?Sized> Deref for NoWaitLockGuard<'_, T>

type Target = T

The resulting type after dereferencing.

source

fn deref(&self) -> &Self::Target

Dereferences the value.

source

impl<T: ?Sized> DerefMut for NoWaitLockGuard<'_, T>

source

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

source
