[−][src]Trait rustc_ap_syntax::visit::Visitor
Each method of the Visitor
trait is a hook to be potentially
overridden. Each method's default implementation recursively visits
the substructure of the input via the corresponding walk
method;
e.g., the visit_mod
method by default calls visit::walk_mod
.
If you want to ensure that your code handles every variant
explicitly, you need to override each method. (And you also need
to monitor future changes to Visitor
in case a new method with a
new default implementation gets introduced.)
