std
An enumeration of possible errors associated with a TryLockResult.
📍work/sync
re-exported from std::sync
An enumeration of possible errors associated with a TryLockResult which
can occur while trying to acquire a lock, from the try_lock method on a
Mutex or the try_read and try_write methods on an RwLock.
Variants§
Poisoned(PoisonError<T>)
The lock could not be acquired because another thread failed while holding the lock.
WouldBlock
The lock could not be acquired at this time because the operation would otherwise block.
