Types

type Spinlock

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

Spinlock implements a lock where each task trying to acquire it busy-waits till the lock becomes available.

func (*Spinlock) Acquire

func (l *Spinlock) Acquire()

Acquire blocks until the lock can be acquired by the currently active task. Any attempt to re-acquire a lock already held by the current task will cause a deadlock.

func (*Spinlock) Release

func (l *Spinlock) Release()

Release relinquishes a held lock allowing other tasks to acquire it. Calling Release while the lock is free has no effect.

func (*Spinlock) TryToAcquire

func (l *Spinlock) TryToAcquire() bool

TryToAcquire attempts to acquire the lock and returns true if the lock could be acquired or false otherwise.
