Struct DefIdsToImplsCollector 

pub(crate) struct DefIdsToImplsCollector<'tcx, 'a> {
    pub(crate) tcx: TyCtxt<'tcx>,
    pub(crate) def_ids_to_impls: &'a mut FxHashMap<LocalDefId, FxHashSet<LocalDefId>>,
    pub(crate) impl_def_id: LocalDefId,
}

Visitor that collects correspondence map between defs and enclosing impls.

Fields

tcx: TyCtxt<'tcx>

def_ids_to_impls: &'a mut FxHashMap<LocalDefId, FxHashSet<LocalDefId>>

impl_def_id: LocalDefId

Implementations

impl<'tcx, 'a> DefIdsToImplsCollector<'tcx, 'a>

pub(crate) fn collect( tcx: TyCtxt<'tcx>, ) -> FxHashMap<LocalDefId, FxHashSet<LocalDefId>>

Trait Implementations

impl<'tcx, 'a> DefIdVisitor<'tcx> for DefIdsToImplsCollector<'tcx, 'a>

const SHALLOW: bool = true

fn skip_assoc_tys(&self) -> bool

fn tcx(&self) -> TyCtxt<'tcx>

fn visit_def_id(&mut self, def_id: DefId, _kind: &str, _descr: &dyn Display)

NOTE: Def-id visiting should be idempotent (or at least produce duplicated errors), because DefIdVisitorSkeleton will use caching and sometimes avoid visiting duplicate def-ids. All the current visitors follow this rule.

type Result = ()

fn skeleton(&mut self) -> DefIdVisitorSkeleton<'_, 'tcx, Self>

Not overridden, but used to actually visit types and traits.

fn visit( &mut self, ty_fragment: impl TypeVisitable<TyCtxt<'tcx>>, ) -> Self::Result

fn visit_trait(&mut self, trait_ref: TraitRef<'tcx>) -> Self::Result

fn visit_predicates( &mut self, predicates: GenericPredicates<'tcx>, ) -> Self::Result

fn visit_clauses(&mut self, clauses: &[(Clause<'tcx>, Span)]) -> Self::Result

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.
