Type Alias rustc_middle::ty::layout::TyAndLayout

pub type TyAndLayout<'tcx> = TyAndLayout<'tcx, Ty<'tcx>>;

Aliased Type

struct TyAndLayout<'tcx> {
    pub ty: Ty<'tcx>,
    pub layout: Layout<'tcx>,
}

Fields

ty: Ty<'tcx>

layout: Layout<'tcx>

Trait Implementations

impl<'tcx> Key for TyAndLayout<'tcx>

type CacheSelector = DefaultCacheSelector<TyAndLayout<'tcx, Ty<'tcx>>>

fn default_span(&self, _: TyCtxt<'_>) -> Span

In the event that a cycle occurs, if no explicit span has been given for a query with key self, what span should we use?

fn key_as_def_id(&self) -> Option<DefId>

If the key is a DefId or DefId–equivalent, return that DefId. Otherwise, return None.

fn ty_adt_id(&self) -> Option<DefId>

impl<'tcx> TypeVisitable<TyCtxt<'tcx>> for TyAndLayout<'tcx, Ty<'tcx>>

fn visit_with<V: TypeVisitor<TyCtxt<'tcx>>>( &self, visitor: &mut V ) -> ControlFlow<V::BreakTy>

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

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.
