Implementations
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
Because lints are scoped lexically, we want to walk nested items in the context of the outer item, so enable deep-walking.
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. Read more
Visits the top-level item and (optionally) nested items / impl items. See
visit_nested_item
for details. Read more
fn visit_fn(
&mut self,
fk: FnKind<'tcx>,
decl: &'tcx FnDecl<'tcx>,
body_id: BodyId,
span: Span,
id: HirId
)
fn visit_variant_data(
&mut self,
s: &'tcx VariantData<'tcx>,
_: Symbol,
_: &'tcx Generics<'tcx>,
_: HirId,
_: Span
)
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. Read more
Like visit_nested_item()
, but for trait items. See
visit_nested_item()
for advice on when to override this
method. Read more
Like visit_nested_item()
, but for impl items. See
visit_nested_item()
for advice on when to override this
method. Read more
Like visit_nested_item()
, but for foreign items. See
visit_nested_item()
for advice on when to override this
method. Read more
When invoking visit_all_item_likes()
, you need to supply an
item-like visitor. This method converts an “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. Read more

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.
