Module visitor 

AST Visitor pattern.

Usage

Implement Visitor for your struct. Override visit_* methods to add logic. Call walk_* within your override to continue recursion (or omit it to stop).

impl Visitor for MyPass {
    fn visit_named_node(&mut self, node: &NamedNode) {
        // Pre-order logic
        walk_named_node(self, node);
        // Post-order logic
    }
}
