type User struct {
	Name    string `json:"name"`
	Email   string `json:"email"`

}

func (u User) Valid() (bool, validator.Errors) {
	return validator.ByJSON(u, validator.Validators{
		"name":    validator.StringRequire(u.Name, validator.Shorter(2)),
		"email":   validator.StringRequire(u.Email, validator.Email()),
		"message": validator.StringOption(u.Message, validator.Longer(10)),
	})
}

func main() {
	user := User{
		Message: "Oops!",
