Expand description
Additional methods for RwLock
s which support recursive read locks.
These are guaranteed to succeed without blocking if
another read lock is held at the time of the call. This allows a thread
to recursively lock a RwLock
. However using this method can cause
writers to starve since readers no longer block if a writer is waiting
for the lock.
Required Methods§
Acquires a shared lock without deadlocking in case of a recursive lock.
Attempts to acquire a shared lock without deadlocking in case of a recursive lock.
Object Safety§
This trait is not object safe.
