Struct rustc_trait_selection::traits::structural_match::Search
source · struct Search<'tcx> {
span: Span,
tcx: TyCtxt<'tcx>,
seen: FxHashSet<DefId>,
adt_const_param: bool,
}
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.
adt_const_param: bool

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.
