# Description Judiciously try to avoid allocations/clone by changing the signature of functions - **Don't pass str by value unnecessarily if only read** - **Don't require a vec in `Sandbox::with_files`** - **Remove unnecessary string clone** - **Fixup unnecessary borrow** - **Use `&str` in shape color instead** - **Vec -> Slice** - **Elide string clone** - **Elide `Path` clone** - **Take &str to elide clone in tests** # User-Facing Changes None # Tests + Formatting This touches many tests purely in changing from owned to borrowed/static data
