Analog json.RawMessage for structures?

Question

go

It is necessary for me that in structure I could put any other structure. Something like

type Packet struct {
  Type  string
  Body  json.RawMessage
}

but for an ordinary structure like

type Page struct {
  Title	string
  Body   *struct{}
}

Answer 1

There is an empty interface specifically for this.

type Page struct {
  Title string
  Body  interface{}
}

In a field of this type, you can put a value of any type in general. If you need to get it from there, you can cast it to the original type via type assertion
. If you just then convert the Page structure to json, then you don’t have to bring anything, json.Marshal itself can do it.
