How to call method from struct without variable

Question

Is it possible to call method from struct without variable with this struct type?

//models.go
type MyStruct struct {
  id int
  name string
}

func (s MyStruct) GetSomeAdditionalData() string {
  return "additional data string"
}

//app.go
func main() {
  fmt.Println(models.MyStruct.GetSomeAdditionalData()) // not works

  var variable models.MyStruct
  fmt.Println(variable.GetSomeAdditionalData()) // it worked
}

Or maybe Go have other method to add some data for struct?

Or maybe I select wrong way to do it? :)

You can use a struct literal or a nil pointer.

MyStruct{}.GetSomeAdditionalData()
(*MyStruct)(nil).GetSomeAdditionalData()
