How do I initialize a composed struct in Go?

Question

Let\'s say I have a struct with another struct embedded in it.

type Base struct {
    ID string
}

type Child struct {
    Base
    a int
    b int
}
         


        

Answer 1

Go issue 9859 proposes a change the the language to support the Child{ ID: id, a: a, b: b } syntax from the question.

Use nested composite literals to initialize a value in a single expression:

child := Child{Base: Base{ID: id}, a: a, b: b}

It is not possible to hide the fact that a field is promoted from an embedded struct.
