Finn Evers 9dd6993e2e gpui_shared_string: Avoid intermediate string allocation when deserializing a SharedString (#65089) ... ## Summary This PR improves how we deserialize SharedStrings. Since we moved to `SmolStr` under the hood some time ago, which takes a string by `impl AsRef<str>` in its constructor, we can get rid here of allocating a string where possible in favor of using a stringvisitor during deserialization. This provides us with some decent improvements. ## Testing The benchmark results are the following: | Case | `from_str` before | `from_str` after | Δ | |---|---:|---:|---:| | short (≤23 B, inline) | 23.1 µs | 11.6 µs | −50% | short, escaped | 33.2 µs | 22.4 µs | −32% | | long (~66 B, heap) | 46.9 µs | 31.4 µs | −33% | | long, escaped | 307.6 µs | 267.6 µs | −13% | ## Self-review - [X] I've reviewed my diff for quality, security, reliability, and performance. - [-] UI changes follow the [checklist](https://zed.dev/docs/development/ui-checklist). - [-] Tests cover the new or changed behavior.
