Rust Code Review

Khononov's Balanced Coupling による Rust コードレビュー。

Coupling Analysis (3 Dimensions)

• Strength: Contract(trait bounds) > Model(shared types) > Functional(fn calls) > Intrusive(field access)
• Distance: Same module=strong OK / Different module=weak preferred / External crate=Contract required
• Volatility: git log --oneline -20 <file> — high change freq + strong coupling = pain

Idiom Checklist

• Newtype for domain types: struct UserId(u64)
• pub(crate) over pub
• No public fields across module boundaries
• ? operator, no .unwrap() in production
• Serde types separate from domain models

Red Flags

• Circular dependencies between modules
• God modules (>30 functions or >15 types)
• Primitive obsession (3+ primitive params)

Output

## Coupling Review: {module}

### Issues
- [{severity}] {issue} — Suggestion: {fix}

### Metrics
- Balance Score: X.XX
- Classification: HighCohesion / LooseCoupling / Acceptable / Pain
