Enum std::sync::TryLockError
pub enum TryLockError<T> {
Poisoned(PoisonError<T>),
WouldBlock,
}
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.
Tuple Fields of Poisoned
0: PoisonError<T>WouldBlock
The lock could not be acquired at this time because the operation would otherwise block.
