Struct BrwLockPiWriteGuard 

pub struct BrwLockPiWriteGuard<'a, Class: LockClass, P: ExclusiveLockPolicy<RawBrwLockPi> = <RawBrwLockPi as RawLock>::DefaultPolicy> { /* private fields */ }

A validation guard representing writer lock ownership and active list participation.

Implementations

impl<'a, Class: LockClass, P: ExclusiveLockPolicy<RawBrwLockPi>> BrwLockPiWriteGuard<'a, Class, P>

pub fn new(lock: &'a BrwLockPi<Class>) -> impl PinInit<Self, Infallible>

where P: ExclusiveLockPolicy<RawBrwLockPi, AcquireArgs = ()>,

Creates a new stack-pinned validation guard initialization block.

pub fn token(&self) -> &LockToken<'a, Class>

Returns a shared reference to the lock proof LockToken.

pub fn token_mut(self: Pin<&mut Self>) -> &mut LockToken<'a, Class>

Returns a mutable reference to the lock proof LockToken inside this pinned projection.

pub fn is_locked_by(&self, target: &BrwLockPi<Class>) -> bool

Returns true if this guard holds the given target lock instance.

pub fn call_unlocked<R, F: FnOnce() -> R>(self: Pin<&mut Self>, f: F) -> R

Temporarily releases the write lock before executing the given callable f and then re-acquires the write lock.

Trait Implementations

impl<'a, Class: LockClass, P: ExclusiveLockPolicy<RawBrwLockPi>> Drop for BrwLockPiWriteGuard<'a, Class, P>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
