Expand description

Name privacy visitor, checks privacy and reports violations. Most of name privacy checks are performed during the main resolution phase, or later in type checking when field accesses and associated items are resolved. This pass performs remaining checks for fields in struct expressions and patterns.

Fields§

§tcx: TyCtxt<'tcx>§maybe_typeck_results: Option<&'tcx TypeckResults<'tcx>>§current_item: LocalDefId

Implementations§

source§

impl<'tcx> NamePrivacyVisitor<'tcx>

source

pub(crate) fn typeck_results(&self) -> &'tcx TypeckResults<'tcx>

Gets the type-checking results for the current body. As this will ICE if called outside bodies, only call when working with Expr or Pat nodes (they are guaranteed to be found only in bodies).

source

pub(crate) fn check_field( &mut self, use_ctxt: Span, span: Span, def: AdtDef<'tcx>, field: &'tcx FieldDef, in_update_syntax: bool )

Trait Implementations§

source§

impl<'tcx> Visitor<'tcx> for NamePrivacyVisitor<'tcx>

source§

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

We want to visit items in the context of their containing module and so forth, so supply a crate for doing a deep walk.

§

type NestedFilter = All

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 more
source§

fn visit_mod(&mut self, _m: &'tcx Mod<'tcx>, _s: Span, _n: HirId)

source§

fn visit_nested_body(&mut self, body: 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_item(&mut self, item: &'tcx Item<'tcx>)

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

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

source§

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

§

type Map = <Self::NestedFilter as NestedFilter<'v>>::Map

source§

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 at rustc_hir::intravisit. 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.
source§

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.
source§

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.
source§

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.
