Hi @sidshehria
After reviewing your code multiple times, it seems you're relatively new to Rust and the DataFusion community. I recommend taking some time to familiarize yourself with the Rust language and its tools to ensure your code is compilable. Once you're comfortable with the language, you'll be in a better position to complete this pull request.
