Generic receiver or something like that

Getting Help
1

I have 3 structs in one application. Those are

type LoginResponse struct {
ResultResponse
Token string json:"Token"
ComercioId string json:"ComercioId"
UsuarioId string json:"UsuarioId"
}

type DepositoPagoResponse struct {
ResultResponse
TransaccionID int json:"TransaccionId"
Producto string json:"Producto"
FechaTransaccion time.Time json:"FechaTransaccion"
MontoTransaccion float64 json:"MontoTransaccion"
}

type VerifyAccountResponse struct {
ResultResponse
Producto string json:"Producto"
Saldo float64 json:"Saldo"
}

type ResultResponse struct {
IsSuccess bool json:"IsSuccess"
Codigo int json:"Codigo"
Mensaje string json:"Mensaje"
}

To set properties in my structs i wrote methods that works like builder pattern. For example

func (r *VerifyAccountResponse) WithSuccess(success bool) *VerifyAccountResponse {
r.IsSuccess = success
return r
}

func (r *VerifyAccountResponse) WithCodigo(codigo int) *VerifyAccountResponse {
codigo, mensaje := GetCodeMessage(codigo)
r.Codigo = codigo
r.Mensaje = mensaje
return r
}

So i wrote soemthing like
r := &LoginResponse{}
r.WithSuccess(true).WithCode(100).WithToken(“123”) and so on. The methods WithSuccess and WithCode are repeated by each struct.
I would like to wrote those methods only one time for the ResultResponse in each parent struct.
I thinking something like a generic function receiver or something like that to avoid wrote those methods for each parent struct.
Is it possible ? If so, please some hints would be useful…

TIA,

I got an easy way to make my code simpler. First, i wrote a function that creates a ResultResponse object and then add a WithResultResponse to each other structs. Something like
response.WithResultResponse(models.BuildResultResponse(true, 1097)).
WithToken(“abc123”).
WithUsuarioId(“usuario_1”).
WithComercioId(“9999”)

What’s the problem with writing:

r := LoginResponse{
	ResultResponse: ResultResponse{
		IsSuccess: true,
		Codigo:    100,
	},
	Token: "123",
}

It’s no a problem just want to know how to deal with generics and receivers.

Thanks!!!
