    "github.com/onrik/pointer"

type User struct {
    ID        int
    Name      string
    Age       *int
    UpdatedAt *time.Time
}

func main() {
  // Set helpers
  user := User{
      ID:        1,
      Name:      "John",
      Age:       pointer.Int(27),
      UpdatedAt: pointer.Time(time.Now()),
  }
  
  // Get helpers
  // instead of
  age := -1
  if user.Age != nil {
      age := *user.Age
  }
  
  // Use
  age := pointer.GetInt(user.Age, -1)
}
