type Variant ¶

type Variant[X, Y any] struct {
	X X
	Y Y
}

A Variant represents a single JSON map entry having two different Go type representations X and Y. After JSON unmarshalling you can check with HasX, HasY which field has been detected, while X is preferred. An example usage is a Client DTO response which can either be struct representing a secret hash, or a simple string response if that's a non-sensitive value.

func (v Variant[X, Y]) HasX() bool

func (v Variant[X, Y]) HasY() bool

func (v Variant[X, Y]) MarshalJSON() ([]byte, error)

func (v *Variant[X, Y]) UnmarshalJSON(bytes []byte) error

func (v Variant[X, Y]) WithX(action func(x *X))

func (v Variant[X, Y]) WithY(action func(y *Y))
