Types

type Mutex

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

Mutex is a mutual exclusion primitive that implements TryLock in addition to Lock and Unlock.

func (*Mutex) Init

func (m *Mutex) Init()

Init initializes the mutex.

func (*Mutex) Lock

func (m *Mutex) Lock()

Lock acquires the mutex. If it is currently held by another goroutine, Lock will wait until it has a chance to acquire it.

func (*Mutex) TryLock

func (m *Mutex) TryLock() bool

TryLock attempts to acquire the mutex without blocking. If the mutex is currently held by another goroutine, it fails to acquire it and returns false.

func (*Mutex) Unlock

func (m *Mutex) Unlock()

Unlock releases the mutex.

type RWMutex

type RWMutex drwmutex.DRWMutex

func (RWMutex) Lock

func (rm RWMutex) Lock()

func (RWMutex) RLock

func (rm RWMutex) RLock()

func (RWMutex) Unlock

func (rm RWMutex) Unlock()
