Module Guidelines

• Each crate should have a clear, single responsibility
• Use pub(crate) for internal APIs
• Minimize dependencies between crates
• Follow Rust module conventions

🚀 Development Workflow

Feature Development

1. Create Issue - Describe the feature or bug
2. Create Branch - Use descriptive branch names
3. Implement Changes - Follow coding standards
4. Write Tests - Ensure adequate test coverage
5. Update Documentation - Keep docs current
6. Submit PR - Follow PR template
7. Code Review - Address review feedback
8. Merge - Squash and merge when approved

Debugging

• Use RUST_LOG=debug for detailed logging
• Use cargo test -- --nocapture for test output
• Use debugger integration in your IDE
• Add temporary debug prints with dbg!() macro

Performance Profiling

• Use cargo bench for benchmarking
• Profile with perf on Linux
• Use cargo flamegraph for flame graphs
• Monitor memory usage with valgrind

🔍 Code Quality

Static Analysis

• Clippy - Rust linter for common mistakes
• Rustfmt - Consistent code formatting
• Cargo Audit - Security vulnerability scanning
• Cargo Deny - License and dependency checking

Testing Requirements

• Minimum 80% test coverage for new code
• All public APIs must have tests
• Integration tests for key workflows
• Performance regression tests

Documentation Requirements

• All public APIs must be documented
• Include usage examples in documentation
• Keep README files up to date
• Document architectural decisions
