如何在父函数中获取子结构名称？

Question

how can i get child struct name in parent func? my online code is here: https://go.dev/play/p/04w5mK0aAgL

type IParent interface {
    TypeName() string
}

type Parent struct{ IParent }

func (p *Parent) TypeName() string {

    if t := reflect.TypeOf(p); t.Kind() == reflect.Ptr {
        return "*" + t.Elem().Name()
    } else {
        return t.Name()
    }
}

type Child struct {
    *Parent
}

func main() {
    var e IParent = &Child{}

    // output: TypeName: *Parent.
    // expected: TypeName: *Child.
    val := e.TypeName()
    fmt.Printf("TypeName: %v.\n", val)
}

the output is TypeName: *Parent. , my expected output is TypeName: *Child. , could someone can give me some suggest?

I think u miss with the concept of struct in go.

type Child struct {
    *Parent
}

func main() {
    var e IParent = &Child{}

Above, clearly if u define the struct Child with Parent as the content of struct, but afterthat u declare the child and output the content. In here so clearly the result is *Parent.
