Golang magic code

1. Golang magic code

Golang Some writing methods are quite “ Devil ” Of , Here is a record of .

1.1. Common data types can have methods

int Band method :

type testint int

func (ti testint) ToString() string {
	return "test_int"
}

func main() {
	a := testint(2)
	fmt.Println(a.ToString())
}

1.2. Verify that a has been implemented interface All the ways

var _ sinkcommon.ISink = new(SinkInfluxDB)

type ISink interface {
	GetInfo() *SinkInfo
	LoadConfig(mConf map[string]interface{}) error
	Write(pts []ISinkPoint) error
}

func (s *SinkInfluxDB) GetInfo() *sinkcommon.SinkInfo {
func (s *SinkInfluxDB) LoadConfig(mConf map[string]interface{}) error {
func (s *SinkInfluxDB) Write(pts []sinkcommon.ISinkPoint) error {
