}Fields§
§op: Operand<Prov>§layout: TyAndLayout<'tcx, Ty<'tcx>>§align: Option<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 an OpTy!
None means “alignment does not matter since this is a by-value operand”
(Operand::Immediate); this field is only relevant for Operand::Indirect.
Also CTFE ignores alignment anyway, so this is for Miri only.

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.
