Trait Implementations

impl Debug for StructEnumVisitor<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx> Visitor<'tcx> for StructEnumVisitor<'tcx>

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 maybe_tcx.

fn maybe_tcx(&mut self) -> Self::MaybeTyCtxt

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, item: &'tcx Item<'tcx>) -> Self::Result

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

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

type Result = ()

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

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 TyCtxt; see maybe_tcx for advice.

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.

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.

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.

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.

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

fn visit_body(&mut self, b: &Body<'v>) -> Self::Result

fn visit_ty(&mut self, t: &'v Ty<'v, AmbigArg>) -> Self::Result

All types are treated as ambiguous types for the purposes of hir visiting in order to ensure that visitors can handle infer vars without it being too error-prone.

fn visit_const_arg(&mut self, c: &'v ConstArg<'v, AmbigArg>) -> Self::Result

All consts are treated as ambiguous consts for the purposes of hir visiting in order to ensure that visitors can handle infer vars without it being too error-prone.
