Struct BrwLockPiWriteGuard 

pub struct BrwLockPiWriteGuard<'a, Class: LockClass> { /* private fields */ }

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

Implementations

impl<'a, Class: LockClass> BrwLockPiWriteGuard<'a, Class>

pub fn project<'__pin>( self: Pin<&'__pin mut Self>, ) -> BrwLockPiWriteGuardProjection<'__pin, 'a, Class>

Pin-projects all fields of Self.

These fields are structurally pinned:

• lock_entry

These fields are not structurally pinned:

• lock
• token

impl<'a, Class: LockClass> BrwLockPiWriteGuard<'a, Class>

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

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 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> Drop for BrwLockPiWriteGuard<'a, Class>

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.

impl<'a, Class: LockClass> HasPinData for BrwLockPiWriteGuard<'a, Class>

type PinData = __ThePinData<'a, Class>

unsafe fn __pin_data() -> Self::PinData

impl<'a, Class: LockClass> PinnedDrop for BrwLockPiWriteGuard<'a, Class>

fn drop(self: Pin<&mut Self>, _: OnlyCallFromDrop)

Executes the pinned destructor of this type.
