pub struct ReadOnlyRwLock<T>(/* private fields */);
Expand description
Read-only wrapper on an Arc<RwLock<T>>
contextual value.
Implementations§
source§impl<T> ReadOnlyRwLock<T>
impl<T> ReadOnlyRwLock<T>
sourcepub fn new(l: Arc<RwLock<RawRwLock, T>>) -> ReadOnlyRwLock<T>
pub fn new(l: Arc<RwLock<RawRwLock, T>>) -> ReadOnlyRwLock<T>
New.
sourcepub fn read(&self) -> RwLockReadGuard<'_, RawRwLock, T>
pub fn read(&self) -> RwLockReadGuard<'_, RawRwLock, T>
Locks this RwLock
with shared read access, blocking the current thread until it can be acquired.
See parking_lot::RwLock::read
for more details.
sourcepub fn read_recursive(&self) -> RwLockReadGuard<'_, RawRwLock, T>
pub fn read_recursive(&self) -> RwLockReadGuard<'_, RawRwLock, T>
Locks this RwLock
with shared read access, blocking the current thread until it can be acquired.
Unlike read
, this method is guaranteed to succeed without blocking if
another read lock is held at the time of the call.
See parking_lot::RwLock::read_recursive
for more details.
sourcepub fn try_read(&self) -> Option<RwLockReadGuard<'_, RawRwLock, T>>
pub fn try_read(&self) -> Option<RwLockReadGuard<'_, RawRwLock, T>>
Attempts to acquire this RwLock
with shared read access.
See parking_lot::RwLock::try_read
for more details.
sourcepub fn try_read_recursive(&self) -> Option<RwLockReadGuard<'_, RawRwLock, T>>
pub fn try_read_recursive(&self) -> Option<RwLockReadGuard<'_, RawRwLock, T>>
Attempts to acquire this RwLock
with shared read access.
See parking_lot::RwLock::try_read_recursive
for more details.
sourcepub fn ptr_eq(&self, other: &ReadOnlyRwLock<T>) -> bool
pub fn ptr_eq(&self, other: &ReadOnlyRwLock<T>) -> bool
Gets if the read-only shared reference is to the same lock as other
.
