error[E0509]: cannot move out of type `S<'_>`, which implements the `Drop` trait
--> $DIR/issue-52059-report-when-borrow-and-drop-conflict.rs:26:13

LL | let p = s.url; p
| ^^^^^

| cannot move out of here
| move occurs because `s.url` has type `&mut std::string::String`, which does not implement the `Copy` trait
| help: consider borrowing here: `&s.url`
error: aborting due to 4 previous errors
