Apply these guidelines when writing or reviewing Rust code. Based on Apollo GraphQL's Rust Best Practices Handbook.
Best Practices Reference
Before reviewing, familiarize yourself with Apollo's Rust best practices. Read ALL relevant chapters in the same turn in parallel. Reference these files when providing feedback:
- Chapter 1 - Coding Styles and Idioms: Borrowing vs cloning, Copy trait, Option/Result handling, iterators, comments
- Chapter 2 - Clippy and Linting: Clippy configuration, important lints, workspace lint setup
- Chapter 3 - Performance Mindset: Profiling, avoiding redundant clones, stack vs heap, zero-cost abstractions
- Chapter 4 - Error Handling: Result vs panic, thiserror vs anyhow, error hierarchies
- Chapter 5 - Automated Testing: Test naming, one assertion per test, snapshot testing
- Chapter 6 - Generics and Dispatch: Static vs dynamic dispatch, trait objects
- Chapter 7 - Type State Pattern: Compile-time state safety, when to use it
- Chapter 8 - Comments vs Documentation: When to comment, doc comments, rustdoc
- Chapter 9 - Understanding Pointers: Thread safety, Send/Sync, pointer types
