Struct OpaqueTypeCollector 

struct OpaqueTypeCollector<'tcx> {
    tcx: TyCtxt<'tcx>,
    opaques: Vec<LocalDefId>,
    item: LocalDefId,
    seen: FxHashSet<LocalDefId>,
    span: Option<Span>,
    mode: CollectionMode,
}

Fields

tcx: TyCtxt<'tcx>

opaques: Vec<LocalDefId>

item: LocalDefId

The DefId of the item which we are collecting opaque types for.

seen: FxHashSet<LocalDefId>

Avoid infinite recursion due to recursive declarations.

span: Option<Span>

mode: CollectionMode

Implementations

impl<'tcx> OpaqueTypeCollector<'tcx>

fn new(tcx: TyCtxt<'tcx>, item: LocalDefId) -> Self

fn span(&self) -> Span

fn visit_spanned(&mut self, span: Span, value: impl TypeVisitable<TyCtxt<'tcx>>)

fn collect_taits_declared_in_body(&mut self)

fn visit_opaque_ty(&mut self, alias_ty: AliasTy<'tcx>)

fn collect_taits_from_defines_attr(&mut self)

Checks the #[define_opaque] attributes on items and collects opaques to define from the referenced types.

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.
