Not support String() implement function?

[rsgok]

Seems like litter not accept costumed String() implement func

Example comparing go-spew

package main

import (
	"github.com/davecgh/go-spew/spew"
	"github.com/sanity-io/litter"
)

func main() {
	TT()
}

type A struct {
	Tag string
	Num int
	InA InA
}

type InA struct {
	Id   int
	Type string
}

func (t InA) String() string {
	return t.Type
}

func TT() {
	a := A{
		Tag: "tag-A",
		Num: 1,
		InA: InA{
			Id:   100,
			Type: "test",
		},
	}
	spew.Dump(a)
	litter.Dump(a)
}

Output compare

(main.A) {
 Tag: (string) (len=5) "tag-A",
 Num: (int) 1,
 InA: (main.InA) test
}
main.A{
  Tag: "tag-A",
  Num: 1,
  InA: main.InA{
    Id: 100,
    Type: "test",
  },
}

Litter doesn't use fmt.Stringer because Litter is meant to produce a format that corresponds to the data structure. If you want to modify the output, you can plug in a custom formatter. You should easily be able to add something that dumps fmt.Stringer types as strings instead.

Have tried custom formatter, seems good.

However, when i use anonymous struct member, output is unexpected. Like I mention in davecgh/go-spew#142

Here is my demo code

package main

import (
	"io"

	"github.com/sanity-io/litter"
)

func main() {
	TT()
}

type A struct {
	Tag string
	Num int
	InA
}

type InA struct {
	Id   int
	Type string
}

func (t InA) String() string {
	return t.Type
}

func (t InA) LitterDump(w io.Writer) {
	w.Write([]byte(t.Type))
}

func TT() {
	a := A{
		Tag: "tag-A",
		Num: 1,
		InA: InA{
			Id:   100,
			Type: "test",
		},
	}
	litter.Dump(a)
}

output is

main.Atest

struct A is missing
