struct Search<'tcx> {
    span: Span,
    tcx: TyCtxt<'tcx>,
    seen: FxHashSet<DefId>,
}
Expand description

This implements the traversal over the structure of a given type to try to find instances of ADTs (specifically structs or enums) that do not implement the structural-match traits (StructuralPartialEq and StructuralEq).

Fields§

§span: Span§tcx: TyCtxt<'tcx>§seen: FxHashSet<DefId>

Tracks ADTs previously encountered during search, so that we will not recur on them again.

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.
