| error[E0596]: cannot borrow `sm.x` as mutable, as it is behind a `&` reference |
| --> $DIR/accidentally-cloning-ref-borrow-error.rs:32:9 |

| LL | foo(&mut sm.x); |
| | ^^^^^^^^^ `sm` is a `&` reference, so the data it refers to cannot be borrowed as mutable |

| LL | let mut sm = sr.clone(); |
| | ^^^^^^^ |
| help: consider annotating `Str` with `#[derive(Clone)]` |
| | |
| LL + #[derive(Clone)] |
| LL | struct Str { |
