进入相同结构类型的结构？

I want a relationship between structs, example:

type A struct {
   X string
   Y int
   *A
}

It's possible this? And if it's possible, what is the right way to marshal and unmarshal to JSON this?

When i marshal this struct to JSON the field A is lost.

The code is correct, but the anonimous filed A is lost because have the same names as the struct. Solution:

type A struct {
   X string
   Y int
   Z *A
}
