Rust Code Quality Guide

When to Use

• Writing new Rust code that requires type conversions or error handling
• Reviewing Rust code for quality issues
• Ensuring code follows best practices for error messages and Clippy compliance
• Fixing Clippy warnings or understanding why certain patterns are discouraged

Quick Reference

• as casting → try_from() + map_err()
• unwrap_or(default) → map_err() with explicit error
• format! → use inline arguments {var}
• Error messages must include the causative value
• #[allow(clippy::...)] only allowed in test code
