Struct PlaceRef

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.
