source · pub struct RwLockReadGuardOwned<T>where
T: 'static,{ /* private fields */ }Expand description
Represents a read guard for an Arc<RwLock<T>> that owns a reference to it.
Implementations§
source§impl<T> RwLockReadGuardOwned<T>
impl<T> RwLockReadGuardOwned<T>
sourcepub fn lock(own: Arc<RwLock<RawRwLock, T>>) -> RwLockReadGuardOwned<T>
pub fn lock(own: Arc<RwLock<RawRwLock, T>>) -> RwLockReadGuardOwned<T>
Lock owned.
See parking_lot::RwLock::read for more details.
sourcepub fn lock_recursive(own: Arc<RwLock<RawRwLock, T>>) -> RwLockReadGuardOwned<T>
pub fn lock_recursive(own: Arc<RwLock<RawRwLock, T>>) -> RwLockReadGuardOwned<T>
Locks this RwLock with shared read access, blocking the current thread until it can be acquired.
See parking_lot::RwLock::read_recursive for more details.
sourcepub fn try_lock(
own: Arc<RwLock<RawRwLock, T>>,
) -> Option<RwLockReadGuardOwned<T>>
pub fn try_lock( own: Arc<RwLock<RawRwLock, T>>, ) -> Option<RwLockReadGuardOwned<T>>
Try lock owned.
See parking_lot::RwLock::try_read for more details.
sourcepub fn try_lock_recursive(
own: Arc<RwLock<RawRwLock, T>>,
) -> Option<RwLockReadGuardOwned<T>>
pub fn try_lock_recursive( own: Arc<RwLock<RawRwLock, T>>, ) -> Option<RwLockReadGuardOwned<T>>
Try lock owned.
See parking_lot::RwLock::try_read for more details.
sourcepub fn map<O>(
guard: RwLockReadGuardOwned<T>,
map: impl FnOnce(&T) -> &O,
) -> MappedRwLockReadGuardOwned<T, O>
pub fn map<O>( guard: RwLockReadGuardOwned<T>, map: impl FnOnce(&T) -> &O, ) -> MappedRwLockReadGuardOwned<T, O>
Make a new MappedRwLockReadGuardOwned for a component of the locked data.
This is an associated function that needs to be
used as RwLockReadGuardOwned::map(...). A method would interfere with methods of
the same name on the contents of the locked data.
