Struct rustc_privacy::ObsoleteVisiblePrivateTypesVisitor

pub(crate) struct ObsoleteVisiblePrivateTypesVisitor<'a, 'tcx> {
    pub(crate) tcx: TyCtxt<'tcx>,
    pub(crate) effective_visibilities: &'a EffectiveVisibilities,
    pub(crate) in_variant: bool,
    pub(crate) old_error_set: HirIdSet,
}

Obsolete visitors for checking for private items in public interfaces. These visitors are supposed to be kept in frozen state and produce an “old error node set”. For backward compatibility the new visitor reports warnings instead of hard errors when the erroneous node is not in this old set.

Fields

tcx: TyCtxt<'tcx>

effective_visibilities: &'a EffectiveVisibilities

in_variant: bool

old_error_set: HirIdSet

Trait Implementations

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

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

We want to visit items in the context of their containing module and so forth, so supply a crate for doing a deep walk.

type NestedFilter = All

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.

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

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

fn visit_generics(&mut self, generics: &'tcx Generics<'tcx>)

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

fn visit_ty(&mut self, t: &'tcx Ty<'tcx>)

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

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

fn visit_block(&mut self, _: &'tcx Block<'tcx>)

fn visit_expr(&mut self, _: &'tcx Expr<'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 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.

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.
