impl<'v> Visitor<'v> for StatCollector<'v>

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

type Map = Map<'v>

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

The default versions of the visit_nested_XXX routines invoke this method to get a map to use. By selecting an enum variant, you control which kinds of nested HIR are visited; see NestedVisitorMap for details. By "nested HIR", we are referring to bits of HIR that are not directly embedded within one another but rather indirectly, through a table in the crate. This is done to control dependencies during incremental compilation: the non-inline bits of HIR can be tracked and hashed separately.

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, trait_item_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, impl_item_id: ImplItemId)

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

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_item(&mut self, i: &'v Item<'v>)

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

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

pub fn visit_foreign_item(&mut self, i: &'v ForeignItem<'v>)

pub fn visit_local(&mut self, l: &'v Local<'v>)

pub fn visit_macro_def(&mut self, macro_def: &'v MacroDef<'v>)

pub fn visit_body(&mut self, b: &'v Body<'v>)

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.
