Enum rustc_codegen_ssa::mir::LocalRef

enum LocalRef<'tcx, V> {
    Place(PlaceRef<'tcx, V>),
    UnsizedPlace(PlaceRef<'tcx, V>),
    Operand(Option<OperandRef<'tcx, V>>),
}

Variants

Place(PlaceRef<'tcx, V>)

UnsizedPlace(PlaceRef<'tcx, V>)

UnsizedPlace(p): p itself is a thin pointer (indirect place). *p is the fat pointer that references the actual unsized place. Every time it is initialized, we have to reallocate the place and update the fat pointer. That’s the reason why it is indirect.

Operand(Option<OperandRef<'tcx, V>>)

Implementations

impl<'a, 'tcx, V: CodegenObject> LocalRef<'tcx, V>

fn new_operand<Bx: BuilderMethods<'a, 'tcx, Value = V>>(
    bx: &mut Bx,
    layout: TyAndLayout<'tcx>
) -> LocalRef<'tcx, V>

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.
