Plugin System in TuskLang with Rust

🔌 Extensible Architecture

TuskLang's plugin system allows you to extend the language's capabilities through modular, loadable components. With Rust's excellent plugin architecture support, you can create powerful, type-safe extensions that integrate seamlessly with the core language.

🎯 Best Practices

1. Plugin Design

- Keep plugins focused and single-purpose - Use clear, descriptive names - Implement proper error handling - Provide comprehensive documentation

2. Performance

- Use async execution for I/O operations - Implement proper resource management - Optimize for common use cases - Monitor resource usage

3. Security

- Validate all inputs - Implement proper access controls - Use secure defaults - Follow security best practices

4. Testing

- Write comprehensive unit tests - Include integration tests - Test error conditions - Benchmark performance

5. Documentation

- Provide clear examples - Document all APIs - Include performance characteristics - Add security considerations

The plugin system in TuskLang with Rust provides a powerful, extensible architecture that allows you to add custom functionality while maintaining type safety and performance.
