type Map = <Self::NestedFilter as NestedFilter<'v>>::Map
§type NestedFilter = None
type NestedFilter = None
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
. Read moresource§fn nested_visit_map(&mut self) -> Self::Map
fn nested_visit_map(&mut self) -> Self::Map
If
type NestedFilter
is set to visit nested items, this method
must also be overridden to provide a map to retrieve nested items. Read moresource§fn visit_nested_item(&mut self, id: ItemId)
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. Read moresource§fn visit_nested_trait_item(&mut self, id: TraitItemId)
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. Read moresource§fn visit_nested_impl_item(&mut self, id: ImplItemId)
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. Read moresource§fn visit_nested_foreign_item(&mut self, id: ForeignItemId)
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. Read moresource§fn visit_nested_body(&mut self, id: BodyId)
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
. Read morefn visit_param(&mut self, param: &'v Param<'v>)

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
