[GO]接口的嵌用继承

package main

import "fmt"

type Humaner interface {
    SayHi()
}

type Personer interface {
    Humaner
    Sing(lrc string)
}

type Student struct {
    name string
    id int
}

//实现接口的sayhi
func (s *Student)SayHi()  {
    fmt.Printf("%s sayhi\n", s.name)
}

func (p *Student)Sing(lrc string)  {
    fmt.Printf("student %s sing %s\n", p.name, lrc)
}

func main() {
　　//定义一个接口的类型的变量
    var i Personer
    s := &Student{"mike", 1}
    i = s
    i.SayHi()
    i.Sing("loving you ")
}

执行结果为

mike sayhi
student mike sing loving you
