Implementations

Trait Implementations

Because we want to track parent items and so forth, enable deep walking so that we walk nested items in the context of their outer items.

Invoked when a nested item is encountered. By default does nothing unless you override nested_visit_map to return other than None, in which case it will walk the item. You probably don’t want to override this method – instead, override nested_visit_map or use the “shallow” or “deep” visit patterns described on itemlikevisit::ItemLikeVisitor. The only reason to override this method is if you want a nested pattern but cannot supply a Map; see nested_visit_map for advice. Read more

Like visit_nested_item(), but for trait items. See visit_nested_item() for advice on when to override this method. Read more

Like visit_nested_item(), but for impl items. See visit_nested_item() for advice on when to override this method. Read more

Like visit_nested_item(), but for foreign items. See visit_nested_item() for advice on when to override this method. Read more

Invoked to visit the body of a function, method or closure. Like visit_nested_item, does nothing by default unless you override nested_visit_map to return other than None, in which case it will walk the body. Read more

Visits the top-level item and (optionally) nested items / impl items. See visit_nested_item for details. Read more

When invoking visit_all_item_likes(), you need to supply an item-like visitor. This method converts an “intra-visit” visitor into an item-like visitor that walks the entire tree. If you use this, you probably don’t want to process the contents of nested item-like things, since the outer loop will visit them as well. Read more
