Struct maitake::sync::spin::RwLockWriteGuard

source ·
pub struct RwLockWriteGuard<'lock, T>
where T: ?Sized,
{ /* private fields */ }
Expand description

An RAII implementation of a “scoped write lock” of a RwLock. When this structure is dropped (falls out of scope), the lock will be unlocked.

The data protected by the RwLock can be mutably accessed through this guard via its Deref and DerefMut implementations.

This structure is created by the write and try_write methods on RwLock.

Trait Implementations§

source§

impl<T, R> AsRef<R> for RwLockWriteGuard<'_, T>
where T: AsRef<R> + ?Sized, R: ?Sized,

source§

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

§

type Target = T

The resulting type after dereferencing.
source§

fn deref(&self) -> &<RwLockWriteGuard<'_, T> as Deref>::Target

Dereferences the value.
source§

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

source§

fn deref_mut(&mut self) -> &mut <RwLockWriteGuard<'_, T> as Deref>::Target

Mutably dereferences the value.
source§

impl<T> Display for RwLockWriteGuard<'_, T>
where T: Display + ?Sized,

source§

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

source§

impl<T> Drop for RwLockWriteGuard<'_, T>
where T: ?Sized,

source§

fn drop(&mut self)

Executes the destructor for this type. Read more
source§

impl<T> Send for RwLockWriteGuard<'_, T>
where T: Send + Sync + ?Sized,

A RwLockWriteGuard is only Send if T is Send and Sync, because it can be used to move a T across thread boundaries, as it allows mutable access to the T that can be used with core::mem::replace or core::mem::swap.

source§

impl<T> Sync for RwLockWriteGuard<'_, T>
where T: Send + Sync + ?Sized,

A RwLockWriteGuard is only Sync if T is Send and Sync, because it can be used to move a T across thread boundaries, as it allows mutable access to the T that can be used with core::mem::replace or core::mem::swap.
