Struct netstack3_core::sync::RwLock
source · pub struct RwLock<T>(/* private fields */);
Expand description
A sync::RwLock
assuming lock poisoning will never occur.
Implementations§
source§impl<T> RwLock<T>
impl<T> RwLock<T>
sourcepub fn read(&self) -> LockGuard<'_, RwLock<T>, RwLockReadGuard<'_, T>>
pub fn read(&self) -> LockGuard<'_, RwLock<T>, RwLockReadGuard<'_, T>>
Locks this rwlock with shared read access, blocking the current thread until it can be acquired.
See sync::RwLock::read
for more details.
§Panics
This method may panic if the calling thread already holds the read or write lock.
sourcepub fn write(&self) -> LockGuard<'_, RwLock<T>, RwLockWriteGuard<'_, T>>
pub fn write(&self) -> LockGuard<'_, RwLock<T>, RwLockWriteGuard<'_, T>>
Locks this rwlock with exclusive write access, blocking the current thread until it can be acquired.
See sync::RwLock::write
for more details.
§Panics
This method may panic if the calling thread already holds the read or write lock.
sourcepub fn into_inner(self) -> T
pub fn into_inner(self) -> T
Consumes this rwlock, returning the underlying data.
sourcepub fn get_mut(&mut self) -> &mut T
pub fn get_mut(&mut self) -> &mut T
Returns a mutable reference to the underlying data.
Since this call borrows the RwLock
mutably, no actual locking needs
to take place. See sync::RwLock::get_mut
for more details.
