# Rust Review Command
Review Rust code for idiomatic patterns and best practices: $ARGUMENTS
## Your Task
1. **Analyze Rust code** for idioms and patterns
2. **Check ownership** - borrowing, lifetimes, unnecessary clones
3. **Review error handling** - proper `?` propagation, no unwrap in production
4. **Verify safety** - unsafe usage, injection, secrets
## Review Checklist
### Safety (CRITICAL)
- [ ] No unchecked `unwrap()`/`expect()` in production paths
- [ ] `unsafe` blocks have `// SAFETY:` comments
- [ ] No SQL/command injection
- [ ] No hardcoded secrets
### Ownership (HIGH)
- [ ] No unnecessary `.clone()` to satisfy borrow checker
- [ ] `&str` preferred over `String` in function parameters
- [ ] `&[T]` preferred over `Vec<T>` in function parameters
- [ ] No excessive lifetime annotations where elision works
### Error Handling (HIGH)
- [ ] Errors propagated with `?`; use `.context()` in `anyhow`/`eyre` application code
- [ ] No silenced errors (`let _ = result;`)
- [ ] `thiserror` for library errors, `anyhow` for applications
### Concurrency (HIGH)
- [ ] No blocking in async context
- [ ] Bounded channels preferred
- [ ] `Mutex` poisoning handled
- [ ] `Send`/`Sync` bounds correct
### Code Quality (MEDIUM)
- [ ] Functions under 50 lines
- [ ] No deep nesting (>4 levels)
- [ ] Exhaustive matching on business enums
- [ ] Clippy warnings addressed

**TIP**: Run `cargo clippy -- -D warnings` and `cargo fmt --check` for automated checks.
