Trait lock_api::RawRwLockRecursive

pub unsafe trait RawRwLockRecursive: RawRwLock {
    fn lock_shared_recursive(&self);
    fn try_lock_shared_recursive(&self) -> bool;
}

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

fn lock_shared_recursive(&self)

Acquires a shared lock without deadlocking in case of a recursive lock.

fn try_lock_shared_recursive(&self) -> bool

Attempts to acquire a shared lock without deadlocking in case of a recursive lock.
