pub struct MPlaceTy<'tcx, Prov = AllocId>where
Prov: Provenance,{
mplace: MemPlace<Prov>,
pub layout: TyAndLayout<'tcx, Ty<'tcx>>,
pub align: Align,
}
Expand description
A MemPlace with its layout. Constructing it is only possible in this module.
Fields§
§mplace: MemPlace<Prov>
§layout: TyAndLayout<'tcx, Ty<'tcx>>
§align: Align
rustc does not have a proper way to represent the type of a field of a repr(packed)
struct:
it needs to have a different alignment than the field type would usually have.
So we represent this here with a separate field that “overwrites” layout.align
.
This means layout.align
should never be used for a MPlaceTy
!

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.
