}

func GetServer

func GetServer() Server

func NewServer

func NewServer(dir string) Server

type ServerImpl

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

func (*ServerImpl) BatchInsert

func (s *ServerImpl) BatchInsert(attr map[string]string) error

attr[key]val

func (*ServerImpl) Close

func (s *ServerImpl) Close() error

func (*ServerImpl) FindAll

func (s *ServerImpl) FindAll() (map[string]string, error)

func (*ServerImpl) FindByKey

func (s *ServerImpl) FindByKey(key string) (data []byte, err error)
