Download_Waste_Manager

**Code Quality & Patterns:** The code uses a simple loop to periodically scan a directory, filter files based on age, and delete them. It's a straightforward implementation of a file cleanup utility. No design patterns are explicitly used. Error handling is basic, using `unwrap` extensively. **Language-Specific Observations:** Standard Rust features like `fs`, `thread`, `PathBuf`, `SystemTime`, and `Duration` are employed. The use of `unwrap` for error handling is a major shortcoming, potentially leading to crashes. No crates or external libraries are utilized, limiting functionality and robustness. **Code Structure:** The code is contained within a single `main` function in `src/main.rs`. The file structure is minimal. Naming conventions are reasonable. There is no clear separation of concerns; all logic resides within `main`. **Specific Improvements:** * **Error Handling:** Replace `unwrap` calls with proper error handling using `match` or the `?` operator to gracefully handle potential issues like file permission errors or inaccessible paths. * **Configuration:** Extract the waste folder path and deletion threshold to configurable parameters (e.g., environment variables or a configuration file) to enhance flexibility. * **Logging:** Add logging to record file deletion attempts (successful and failed) for better monitoring and debugging. * **Concurrency:** Consider using a more robust asynchronous approach for better performance when dealing with numerous files, potentially using Tokio or async-std. * **Testing:** Add unit and integration tests to verify the functionality and improve reliability. **Impactful Insights:** * **Critical security vulnerabilities:** The high number of critical issues needs immediate attention. * **Robust error handling:** Replace `unwrap()` with proper error handling using `?` or `match`. * **Configuration externalization:** Move hardcoded paths to configuration for flexibility. * **Logging implementation:** Track file deletions for monitoring and debugging. * **Asynchronous operations:** Use Tokio or async-std for efficient concurrency.
