error[E0382]: use of moved value: `x`
--> $DIR/union-move.rs:26:18

LL | fn test1(x: U1) {

note: consider changing this parameter type in function `move_out` to borrow instead if owning the value isn't necessary

error[E0509]: cannot move out of type `U2`, which implements the `Drop` trait
--> $DIR/union-move.rs:49:18
|
LL | move_out(x.f1_nocopy);
| ^^^^^^^^^^^
| |
| cannot move out of here
| move occurs because `x.f1_nocopy` has type `ManuallyDrop<RefCell<i32>>`, which does not implement the `Copy` trait

help: consider cloning the value if the performance cost is acceptable

LL | move_out(x.f1_nocopy.clone());
