It seems like background() must be provided by classes using this trait. How about adding it as abstract method to this trait?
                                                                                   (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-call   annotation

It seems like linkers() must be provided by classes using this trait. How about adding it as abstract method to this trait?
                                                                                   (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-call   annotation
