普通结构体嵌套

普通结构体嵌套，嵌套结构体可以通过 .子变量.方法 的方式获取被嵌套的属性和方法

type Person struct {
    name string
    sex int
}

func (person *Person) getName() string {
    return person.name
}

type Student struct {
    person Person
    work string
}

func (student *Student) workName() string {
    return student.work
}

func TestStruct(t *testing.T) {
    student := &Student{work:"game"}
    student.person = Person{name:"yanghunahuan", sex:1}

    t.Log(student.person.getName()) //yanghuanhuan
    t.Log(student.person.sex) //1
}

匿名嵌套

匿名嵌套之后，嵌套者可以直接获取到被嵌套者的属性和方法

type Person struct {
    name string
    sex int
}

func (person *Person) getName() string {
    return person.name
}

type Student struct {
    Person
    work string
}

func (student *Student) workName() string {
    return student.work
}

func TestStruct(t *testing.T) {
    student := &Student{work:"game"}
    student.Person = Person{name:"yanghunahuan", sex:1}

    t.Log(student.getName()) //yanghuanhuan
    t.Log(student.sex) //1

}
