    &mut self,
    id: HirId,
    attrs: &'tcx [Attribute],

) 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.

Trait Implementations

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

type Map = Map<'tcx>

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

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

pub 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 nested_visit_map to return other than None, in which case it will walk the body.

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

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

pub 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.

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

pub fn visit_pat(&mut self, p: &'tcx Pat<'tcx>)

pub fn visit_expr(&mut self, e: &'tcx Expr<'tcx>)

pub fn visit_stmt(&mut self, s: &'tcx Stmt<'tcx>)

pub fn visit_fn(
    &mut self,
    fk: FnKind<'tcx>,
    decl: &'tcx FnDecl<'tcx>,
    body_id: BodyId,
    span: Span,
    id: HirId
)

pub fn visit_variant_data(
    &mut self,
    s: &'tcx VariantData<'tcx>,
    _: Symbol,
    _: &'tcx Generics<'tcx>,
    _: HirId,
    _: Span
)

pub fn visit_struct_field(&mut self, s: &'tcx StructField<'tcx>)

pub fn visit_variant(
    &mut self,
    v: &'tcx Variant<'tcx>,
    g: &'tcx Generics<'tcx>,
    item_id: HirId
)

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

pub fn visit_name(&mut self, sp: Span, name: Symbol)

pub fn visit_mod(&mut self, m: &'tcx Mod<'tcx>, s: Span, n: HirId)

pub fn visit_path(&mut self, p: &'tcx Path<'tcx>, id: HirId)

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

pub fn visit_nested_item(&mut self, id: ItemId)

Invoked when a nested item is encountered. By default does nothing unless you override nested_visit_map to return other than None, in which case it will walk the item. You probably don't want to override this method -- instead, override nested_visit_map 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.

pub 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.

pub 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.

pub fn as_deep_visitor(&mut self) -> DeepVisitor<'_, Self>

When invoking visit_all_item_likes(), you need to supply an item-like visitor. This method converts a "intra-visit" visitor into an item-like visitor that walks the entire tree. If you use this, you probably don't want to process the contents of nested item-like things, since the outer loop will visit them as well.
