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

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.
