Fields

arena: &'tcx WorkerLocal<Arena<'tcx>>

The arena that types, regions, etc. are allocated from.

type_: ShardedHashMap<Interned<'tcx, TyS<'tcx>>, ()>

Specifically use a speedy hash algorithm for these hash sets, since they’re accessed quite often.

Implementations

impl<'tcx> CtxtInterners<'tcx>

fn new(arena: &'tcx WorkerLocal<Arena<'tcx>>) -> CtxtInterners<'tcx>

fn intern_ty(&self, kind: TyKind<'tcx>) -> Ty<'tcx>

Interns a type.

    &self,
    kind: Binder<'tcx, PredicateKind<'tcx>>
) -> &'tcx PredicateInner<'tcx>

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
