• Basic Functions

  this is basic function you can use to validate your data:

  if err != nil {
      log.Println(err)
  }
  if !ok {
      // bla bla bla
  }

  in struct you can use govals tag like this:

  Name    string `govals:"len, max=22, min=10"`
  Age     int8   `govals:"len, min=18, max=20"`
