Expand description

Type used to hash an ast element. This is different from the Hash trait on ast types as this trait would consider IDs and spans.

All expressions kind are hashed, but some might have a weaker hash.

Fields§

§cx: &'a LateContext<'tcx>

Context used to evaluate constant expressions.

§maybe_typeck_results: Option<&'tcx TypeckResults<'tcx>>§s: FxHasher
