Trait Implementations§

source§

impl<'a, 'hir> Visitor<'hir> for NodeCollector<'a, 'hir>

source§

fn visit_nested_item(&mut self, item: ItemId)

Because we want to track parent items and so forth, enable deep walking so that we walk nested items in the context of their outer items.

source§

fn visit_nested_trait_item(&mut self, item_id: TraitItemId)

Like visit_nested_item(), but for trait items. See visit_nested_item() for advice on when to override this method.
source§

fn visit_nested_impl_item(&mut self, item_id: ImplItemId)

Like visit_nested_item(), but for impl items. See visit_nested_item() for advice on when to override this method.
source§

fn visit_nested_foreign_item(&mut self, foreign_id: ForeignItemId)

Like visit_nested_item(), but for foreign items. See visit_nested_item() for advice on when to override this method.
source§

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.
source§

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

source§

fn visit_item(&mut self, i: &'hir Item<'hir>)
