Idiomatic way to embed struct with custom MarshalJSON() method

Question

Given the following structs:

type Person {
    Name string `json:\"name\"`
}

type Employee {
    Person
    JobRole string `json:\"jobRole\"`
}

<

Answer 1

Don't put MarshalJSON on Person since that's being promoted to the outer type. Instead make a type Name string and have Name implement MarshalJSON. Then change Person to

type Person struct {
    Name Name `json:"name"`
}

Update

To solve this more generically you're going to have to implement MarshalJSON on the outer type. Methods on the inner type are promoted to the outer type so you're not going to get around that. You could have the outer type call the inner type's MarshalJSON then unmarshal that into a generic structure like map[string]interface{} and add your own fields. This example does that but it has a side effect of changing the order of the final output fields
