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.
