Struct zng_app_context::RwLockWriteGuardOwned
source · pub struct RwLockWriteGuardOwned<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> RwLockWriteGuardOwned<T>
impl<T> RwLockWriteGuardOwned<T>
sourcepub fn lock(own: Arc<RwLock<T>>) -> Self
pub fn lock(own: Arc<RwLock<T>>) -> Self
Lock owned.
See parking_lot::RwLock::write for more details.
sourcepub fn try_lock(own: Arc<RwLock<T>>) -> Option<Self>
pub fn try_lock(own: Arc<RwLock<T>>) -> Option<Self>
Lock owned.
See parking_lot::RwLock::try_write for more details.
sourcepub fn map<O>(
guard: Self,
map: impl FnOnce(&mut T) -> &mut O,
) -> MappedRwLockWriteGuardOwned<T, O>
pub fn map<O>( guard: Self, map: impl FnOnce(&mut T) -> &mut O, ) -> MappedRwLockWriteGuardOwned<T, O>
Make a new MappedRwLockReadGuardOwned for a component of the locked data.
This is an associated function that needs to be
used as MappedRwLockReadGuardOwned::map(...). A method would interfere with methods of
the same name on the contents of the locked data.
