Types

type IdWorker

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

func NewIdWorker

func NewIdWorker(workerId, dataCenterId, epoch int64) (error, *IdWorker)

NewIdWorker new worker

func (*IdWorker) GenTime

func (i *IdWorker) GenTime() int64

GenTime 获取当前时间, 单位是毫秒

func (*IdWorker) GetDataCenterID

func (i *IdWorker) GetDataCenterID() int64

GetDataCenterID 获得datacenterID

func (*IdWorker) GetWorkerId

func (i *IdWorker) GetWorkerId() int64

GetWorkerId 获得workerID

func (*IdWorker) NextId

func (i *IdWorker) NextId() (error, int64)

NextId 生成一个ID
