+error[E0382]: use of moved value: `wrapper.inner`
+ --> $DIR/decl-macro-illegal-copy.rs:32:9
+ |
+LL | $wrapper.inner
+ | -------------- value moved here
+...
+LL | wrapper.inner,
+ | ^^^^^^^^^^^^^ value used here after move
+ |
+ = note: move occurs because `wrapper.inner` has type `NonCopy`, which does not implement the `Copy` trait
+
+error: aborting due to previous error
