Struct miri::interpret::LocalState

source ·
pub struct LocalState<'tcx, Prov = AllocId>where
    Prov: Provenance,
{ pub value: LocalValue<Prov>, pub layout: Cell<Option<TyAndLayout<'tcx, Ty<'tcx>>>>, }
Expand description

State of a local variable including a memoized layout

Fields

value: LocalValue<Prov>layout: Cell<Option<TyAndLayout<'tcx, Ty<'tcx>>>>

Don’t modify if Some, this is only used to prevent computing the layout twice

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
