Struct parking_lot::RwLockReadGuard
[−]
[src]
#[must_use] pub struct RwLockReadGuard<'a, T: ?Sized + 'a> { /* fields omitted */ }
RAII structure used to release the shared read access of a lock when dropped.
Methods
impl<'a, T: ?Sized + 'a> RwLockReadGuard<'a, T>
[src]
fn unlock_fair(self)
Unlocks the RwLock
using a fair unlock protocol.
By default, RwLock
is unfair and allow the current thread to re-lock
the rwlock before another has the chance to acquire the lock, even if
that thread has been blocked on the RwLock
for a long time. This is
the default because it allows much higher throughput as it avoids
forcing a context switch on every rwlock unlock. This can result in one
thread acquiring a RwLock
many more times than other threads.
However in some cases it can be beneficial to ensure fairness by forcing
the lock to pass on to a waiting thread if there is one. This is done by
using this method instead of dropping the RwLockReadGuard
normally.
