pub struct RwLock<T: ?Sized> { /* private fields */ }
Expand description
A reader-writer lock, the same as std::sync::RwLock
.
Unlike std::sync::RwLock
, the same thread is never allowed to acquire the read side of a
RwLock
more than once. The std
version is ambiguous about what behavior is allowed here, so
we choose the most conservative one.
Implementations§
source§impl<T: ?Sized> RwLock<T>
impl<T: ?Sized> RwLock<T>
sourcepub fn read(&self) -> LockResult<RwLockReadGuard<'_, T>>
pub fn read(&self) -> LockResult<RwLockReadGuard<'_, T>>
Locks this rwlock with shared read access, blocking the current thread until it can be acquired.
sourcepub fn write(&self) -> LockResult<RwLockWriteGuard<'_, T>>
pub fn write(&self) -> LockResult<RwLockWriteGuard<'_, T>>
Locks this rwlock with exclusive write access, blocking the current thread until it can be acquired.
sourcepub fn try_read(&self) -> TryLockResult<RwLockReadGuard<'_, T>>
pub fn try_read(&self) -> TryLockResult<RwLockReadGuard<'_, T>>
Attempts to acquire this rwlock with shared read access.
If the access could not be granted at this time, then Err is returned. This function does not block.
Note that unlike std::sync::RwLock::try_read
, if the current thread already holds this
read lock, try_read
will return Err.
sourcepub fn try_write(&self) -> TryLockResult<RwLockWriteGuard<'_, T>>
pub fn try_write(&self) -> TryLockResult<RwLockWriteGuard<'_, T>>
Attempts to acquire this rwlock with shared read access.
If the access could not be granted at this time, then Err is returned. This function does not block.
sourcepub fn into_inner(self) -> LockResult<T>where
T: Sized,
pub fn into_inner(self) -> LockResult<T>where
T: Sized,
Consumes this RwLock
, returning the underlying data
