pub unsafe trait RawRwLockRecursive: RawRwLock {
// Required methods
fn lock_shared_recursive(&self);
fn try_lock_shared_recursive(&self) -> bool;
}
Expand description
Additional methods for RwLocks 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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
