Struct rustc_ty_utils::opaque_types::OpaqueTypeCollector

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

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>

Implementations

Trait Implementations

impl<'tcx> TypeVisitor<TyCtxt<'tcx>> for OpaqueTypeCollector<'tcx>

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.
