Enum std::sync::TryLockError

1.0.0 · source ·
pub enum TryLockError<T> {
    Poisoned(PoisonError<T>),
    WouldBlock,
}
Expand description

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§

§1.0.0

Poisoned(PoisonError<T>)

The lock could not be acquired because another thread failed while holding the lock.

§1.0.0

WouldBlock

The lock could not be acquired at this time because the operation would otherwise block.
