[INFO] [stdout] 10 |     pub basename: SmallString,
[INFO] [stdout]    |     ^^^^^^^^^^^^^^^^^^^^^^^^^ move occurs because `self.basename` has type `small_string::SmallString`, which does not implement the `Copy` trait
[INFO] [stdout]    |
[INFO] [stdout]    = note: `#[derive(Clone)]` triggers a move because taking references to the fields of a packed struct is undefined behaviour
[INFO] [stdout]    = note: this error originates in the derive macro `Clone` (in Nightly builds, run with -Z macro-backtrace for more info)
