Advice function needs argument not used in function, how to avoid compiler warning?

[Jean Louis]

I realize that advice function need argument such as &rest args, but I
am not using it in the function. And I do not understand what is that
argument receiving. Anybody may explain it?

I have to do (ignore args) to avoid compiler warning. What does args receive?

(defun hyperscope-after-sort (&rest args)
  (ignore args)
  (hyperscope-highlight))

(advice-add 'tabulated-list-col-sort :after 'hyperscope-after-sort)
(advice-add 'tabulated-list-sort :after 'hyperscope-after-sort)
