Visits all items in the crate in some deterministic (but unspecified) order. If you just need to process every item, but don't care about nesting, this method is the best choice.
If you do care about nesting -- usually because your algorithm
follows lexical scoping rules -- then you want a different
approach. You should override visit_nested_item
in your
visitor and then call intravisit::walk_crate
instead.
