func (*Service) TryAcquire ¶
func (s *Service) TryAcquire(ctx context.Context, operation oplock.Operation, duration time.Duration) (acquired bool, entry oplock.LockEntry, err error)
TryAcquire will attempt to obtain a lock for the supplied operation name for the specified duration. If it succeeds then the returned boolean (acquired) will be true, else false. The lock entry associated with the last successful acquisition is also returned. Given the lock was acquired successfully this will be the entry just created.
