Tips and Tricks

✓Use consistent JSON structure with representative data to generate more accurate Rust struct definitions
✓Enable derive traits like Serialize and Deserialize to make your generated structs compatible with JSON libraries
✓Review field types carefully as the tool infers them from JSON values; adjust precision for numbers as needed
✓For complex nested JSON structures, consider converting in sections and then combining the generated structs manually
