error[E0133]: borrow of layout constrained field with interior mutability is unsafe and requires unsafe function or block
--> $DIR/ranged_ints3_match.rs:11:17
|
LL | NonZero(ref x) => { x }
| ^^^^^ borrow of layout constrained field with interior mutability
|
= note: references to fields of layout constrained fields lose the constraints. Coupled with interior mutability, the field can be changed to invalid values
error[E0133]: mutation of layout constrained field is unsafe and requires unsafe function or block
--> $DIR/ranged_ints3_match.rs:17:23

LL | match y { NonZero(ref mut y) => { y } };
| ^^^^^^^^^ mutation of layout constrained field

= note: mutating layout constrained fields cannot statically be checked for valid values
error: aborting due to 2 previous errors
