Types

type HashFunc

type HashFunc func(interface{}) uint32

HashFunc represents a hash function for string

type IDMutex

type IDMutex interface {
	LockID(identifier interface{})
	UnlockID(identifier interface{})
}

IDMutex is an interface which can lock on specific comparable identifier

func NewIDMutex

func NewIDMutex(numShard uint32, hashFn HashFunc) IDMutex

NewIDMutex create a new IDLock

type Mutex

type Mutex interface {
	Lock(context.Context) error
	Unlock()
}

Mutex accepts a context in its Lock method. It blocks the goroutine until either the lock is acquired or the context is closed.

func NewMutex

func NewMutex() Mutex

NewMutex creates a new RWMutex
