§

type Map = <Self::NestedFilter as NestedFilter<'v>>::Map

§

type NestedFilter = None

Override this type to control which nested HIR are visited; see NestedFilter for details. If you override this type, you must also override nested_visit_map. Read more
§

type Result = ()

The result type of the visit_* methods. Can be either (), or ControlFlow<T>.
source§

fn nested_visit_map(&mut self) -> Self::Map

If type NestedFilter is set to visit nested items, this method must also be overridden to provide a map to retrieve nested items.
source§

fn visit_nested_item(&mut self, id: ItemId) -> Self::Result

Invoked when a nested item is encountered. By default, when Self::NestedFilter is nested_filter::None, this method does nothing. You probably don’t want to override this method – instead, override Self::NestedFilter or use the “shallow” or “deep” visit patterns described at rustc_hir::intravisit. 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.
source§

fn visit_nested_trait_item(&mut self, id: TraitItemId) -> Self::Result

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

fn visit_nested_impl_item(&mut self, id: ImplItemId) -> Self::Result

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

fn visit_nested_foreign_item(&mut self, id: ForeignItemId) -> Self::Result

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

fn visit_nested_body(&mut self, id: BodyId) -> Self::Result

Invoked to visit the body of a function, method or closure. Like visit_nested_item, does nothing by default unless you override Self::NestedFilter.
source§

fn visit_param(&mut self, param: &'v Param<'v>) -> Self::Result

source§

fn visit_item(&mut self, i: &'v Item<'v>) -> Self::Result

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