golang 如何判断继承

type Person struct {
    name string
    age  int
}

type Student struct {
    Person
    grade int
}

s := Student{
    Person: Person{
        name: "Alice",
        age:  18,
    },
    grade: 3,
}
fmt.Println(s.name)   // Alice
fmt.Println(s.age)    // 18
fmt.Println(s.grade)  // 3

type Person struct {
    name string
    age  int
}

type Student struct {
    Person
    grade int
}

func main() {
    s := Student{}
    p := Person{}

    if reflect.TypeOf(s).AssignableTo(reflect.TypeOf(p)) {
        fmt.Println("s is assignable to p")
    } else {
        fmt.Println("s is not assignable to p")
    }

    if reflect.TypeOf(p).AssignableTo(reflect.TypeOf(s)) {
        fmt.Println("p is assignable to s")
    } else {
        fmt.Println("p is not assignable to s")
    }

    if reflect.TypeOf(s).ConvertibleTo(reflect.TypeOf(p)) {
        fmt.Println("s is convertible to p")
    } else {
        fmt.Println("s is not convertible to p")
    }

    if reflect.TypeOf(p).ConvertibleTo(reflect.TypeOf(s)) {
        fmt.Println("p is convertible to s")
    } else {
        fmt.Println("p is not convertible to s")
    }
}

s is assignable to p
p is not assignable to s
s is not convertible to p
p is not convertible to s
