Download_Waste_Manager

**Code Quality & Patterns:** The code uses a simple loop to iteratively check for and delete files older than a threshold. It lacks error handling beyond basic `unwrap()` calls. No design patterns are explicitly used. The implementation is straightforward but prone to failure if file operations encounter issues. **Language-Specific Observations:** The code utilizes standard Rust features like `PathBuf`, `SystemTime`, and `Duration` effectively. However, the overuse of `unwrap()` ignores potential errors, representing a weakness. The lack of any crates or external libraries limits functionality and reusability. **Code Structure:** The code is contained within a single `main` function in `src/main.rs`. The file structure is minimal. Naming conventions are generally clear but could be improved (e.g., more descriptive variable names). Separation of concerns is lacking; all logic resides in `main`. **Specific Improvements:** * **Robust Error Handling:** Replace `unwrap()` with proper error handling using `match` or `?` to gracefully handle potential I/O errors. Log errors comprehensively. * **Configuration:** Externalize the `waste_folder_path` and `deletion_threshold` into a configuration file (e.g., TOML or YAML) to make it easily configurable. * **Modularization:** Break down the `main` function into smaller, more manageable functions (e.g., `get_files`, `filter_old_files`, `delete_files`). * **Testing:** Add unit tests to verify the file age filtering and deletion logic. * **Rate Limiting:** Introduce more sophisticated rate limiting instead of a fixed sleep to prevent overwhelming the system. **Impactful Insights:** * **Error Handling:** Implement robust error handling to prevent crashes. * **Configuration:** Externalize settings for flexibility. * **Modularity:** Refactor for better maintainability and readability. * **Testing:** Add comprehensive unit tests. * **Rate Limiting:** Improve resource management with sophisticated rate limiting.
