Dealing with embedded structs

Fields of a struct type will be encoded as JSON objects. If there are embedded structs, then the encoder has two options: encode the embedded struct at the same level as the enclosing struct or as a new JSON object.

How to do it...

1. Use JSON tags to name enclosing struct fields and the embedded struct fields:

   type Enclosing struct {
        Field string `json:"field"`
        Embedded
   }
   type Embedded struct {
        Field string `json:"embeddedField"`
   }

2. Use json.Marshal to encode the struct as a JSON object:

   enc := Enclosing{
        Field: "enclosing",
        Embedded: Embedded{
             Field: "embedded",
        },
   }
   data, err = json.Marshal(enc)
   // {"field":"enclosing","embeddedField":&quot...
