Trait Implementations

The default versions of the visit_nested_XXX routines invoke this method to get a map to use. By selecting an enum variant, you control which kinds of nested HIR are visited; see NestedVisitorMap for details. By “nested HIR”, we are referring to bits of HIR that are not directly embedded within one another but rather indirectly, through a table in the crate. This is done to control dependencies during incremental compilation: the non-inline bits of HIR can be tracked and hashed separately. Read more

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
