fillstruct

fillstruct

fillstruct - fills a struct literal with default values

For example, given the following types,

type User struct {
	ID   int64
	Name string
	Addr *Address
}

type Address struct {
	City   string
	ZIP    int
	LatLng [2]float64
}

the following struct literal

var frank = User{}

becomes:

var frank = User{
	ID:   0,
	Name: "",
	Addr: &Address{
		City: "",
		ZIP:  0,
		LatLng: [2]float64{
			0.0,
			0.0,
		},
	},
}

after applying fillstruct.
