Implementations

impl<'tcx, T: LateLintPass<'tcx>> LateContextAndPass<'tcx, T>

fn with_lint_attrs<F>(&mut self, id: HirId, f: F)where
    F: FnOnce(&mut Self),

Merge the lints specified by any lint attributes into the current lint context, call the provided function, then reset the lints in effect to their previous state.

fn with_param_env<F>(&mut self, id: HirId, f: F)where
    F: FnOnce(&mut Self),

fn process_mod(&mut self, m: &'tcx Mod<'tcx>, n: HirId)

Trait Implementations

impl<'tcx, T: LateLintPass<'tcx>> Visitor<'tcx> for LateContextAndPass<'tcx, T>

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

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

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_nested_body(&mut self, body_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.

fn visit_param(&mut self, param: &'tcx Param<'tcx>)

fn visit_body(&mut self, body: &'tcx Body<'tcx>)

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

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

fn visit_attribute(&mut self, attr: &'tcx Attribute)

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.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
