Download_Waste_Manager

**Code Quality & Patterns:** The code uses a simple, imperative approach with a main loop for file deletion based on age. No design patterns are explicitly used. Error handling is basic (`unwrap()`). **Language-Specific Observations:** Standard Rust features like `PathBuf`, `SystemTime`, `Duration`, and file I/O are used. The lack of error handling beyond `unwrap()` is a significant weakness. No crates or external libraries are used. **Code Structure:** The code is contained in a single `main.rs` file. Naming conventions are generally clear (`waste_folder_path`, `deletion_threshold`). Separation of concerns is minimal; all logic resides within `main`. **Specific Improvements:** * **Robust Error Handling:** Replace `unwrap()` with proper error handling (e.g., `match` statements or the `?` operator) to prevent crashes. * **Configuration:** Externalize the `waste_folder_path` and `deletion_threshold` to a configuration file. * **Logging:** Implement proper logging for debugging and monitoring. * **Testing:** Add unit tests to verify file deletion logic. * **Concurrency:** Consider using more sophisticated concurrency mechanisms for improved performance if the directory to be checked is very large. **Impactful Insights:** * **Error prone:** Over-reliance on `unwrap()` risks crashes. * **Fragile:** No configuration or robust error handling. * **Untested:** Lacks unit tests, increasing risk of bugs. * **Improve:** Add configuration, error handling, logging, and tests. * **Scalability:** Consider concurrency for larger datasets.
