Implementations

impl<'a, 'tcx> Annotator<'a, 'tcx>

fn annotate<F>( &mut self, def_id: LocalDefId, item_sp: Span, fn_sig: Option<&'tcx FnSig<'tcx>>, kind: AnnotationKind, inherit_deprecation: InheritDeprecation, inherit_const_stability: InheritConstStability, inherit_from_parent: InheritStability, visit_children: F )where F: FnOnce(&mut Self),

Determine the stability for a node based on its attributes and inherited stability. The stability is recorded in the index and used as the parent. If the node is a function, fn_sig is its signature.

fn recurse_with_stability_attrs( &mut self, depr: Option<DeprecationEntry>, stab: Option<Stability>, const_stab: Option<ConstStability>, f: impl FnOnce(&mut Self) )

Trait Implementations

impl<'a, 'tcx> Visitor<'tcx> for Annotator<'a, 'tcx>

type NestedFilter = All

Because stability levels are scoped lexically, we want to walk nested items in the context of the outer item, so enable deep-walking.

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.

fn visit_item(&mut self, i: &'tcx Item<'tcx>)

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

fn visit_trait_item(&mut self, ti: &'tcx TraitItem<'tcx>)

fn visit_impl_item(&mut self, ii: &'tcx ImplItem<'tcx>)

fn visit_variant(&mut self, var: &'tcx Variant<'tcx>)

fn visit_field_def(&mut self, s: &'tcx FieldDef<'tcx>)

fn visit_foreign_item(&mut self, i: &'tcx ForeignItem<'tcx>)

fn visit_generic_param(&mut self, p: &'tcx GenericParam<'tcx>)

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

fn visit_nested_item(&mut self, id: ItemId)

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.

fn visit_nested_trait_item(&mut self, id: TraitItemId)

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

fn visit_nested_impl_item(&mut self, id: ImplItemId)

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

fn visit_nested_foreign_item(&mut self, id: ForeignItemId)

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

fn visit_nested_body(&mut self, id: BodyId)

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
