This is particularly useful for avoiding greedy visiting when only a shallow parse is needed, e.g. to obtain method signatures, while skipping the methods' bodies.
I chose to pass a
skip_children: &mut bool
(with default valuefalse
), rather than adding anenum Children { Skip, Visit }
and havingfn visit_*
return-> Children
(or whatever a better name would be), as the former allows for ignoring (for non-skipping semantics), while the latter would require aDefault::default()
as the last line of every overridden method regardless.With
_semantics: &Semantics
removed the method signatures should be fairly clean again.(Marking this as "draft" for now as it will result in a merge conflict. I'll do a manual rebase when it's time.)
