fn process_macro_use(&mut self, _span: Span)

Extracts macro use and definition information from the AST node defined by the given NodeId, using the expansion information from the node’s span.

If the span is not macro-generated, do nothing, else use callee and callsite spans to record macro definition and use data, using the mac_uses and mac_defs sets to prevent multiples.

Trait Implementations

impl<'tcx> Visitor<'tcx> for DumpVisitor<'tcx>

type Map = Map<'tcx>

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.

fn visit_item(&mut self, item: &'tcx Item<'tcx>)

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

fn visit_generics(&mut self, generics: &'tcx Generics<'tcx>)

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

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

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

fn visit_arm(&mut self, arm: &'tcx Arm<'tcx>)

fn visit_qpath(&mut self, path: &'tcx QPath<'tcx>, id: HirId, _: Span)

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

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

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

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.

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.

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.

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.

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

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

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

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 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
