Struct rustc_codegen_ssa::mir::place::PlaceRef
source · pub struct PlaceRef<'tcx, V> {
pub val: PlaceValue<V>,
pub layout: TyAndLayout<'tcx>,
}
Fields§
§val: PlaceValue<V>
The location and extra runtime properties of the place.
layout: TyAndLayout<'tcx>
The monomorphized type of this place, including variant information.
You probably shouldn’t use the alignment from this layout;
rather you should use the .val.align
of the actual place,
which might be different from the type’s normal alignment.

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.
