Function no_handle_classes 

fn no_handle_classes(restored: &[&str], field_error: &[&str]) -> Vec<String>

The classes of refuse_no_handle: restored, then field_error, then NO_HANDLE_CLASS, each class once at its last place. The two lists usually end in the package’s one parent class (["pkg_saved", "pkg_error"] and ["pkg_field", "pkg_error"]), which then follows both specific classes, as a class vector goes from specific to general.
