Types

type SpinLock

type SpinLock struct {
	// contains filtered or unexported fields
}

SpinLock implements a simple atomic spin lock, the zero value for a SpinLock is an unlocked spinlock.

func (*SpinLock) Lock

func (sl *SpinLock) Lock()

Lock locks sl. If the lock is already in use, the caller blocks until Unlock is called

func (*SpinLock) String

func (sl *SpinLock) String() string

String is human readable lock state

func (*SpinLock) TryLock

func (sl *SpinLock) TryLock() bool

TryLock will try to lock sl and return whether it succeed or not without blocking.

func (*SpinLock) Unlock

func (sl *SpinLock) Unlock()

Unlock unlocks sl, unlike [Mutex.Unlock](http://golang.org/pkg/sync/#Mutex.Unlock), there's no harm calling it on an unlocked SpinLock
