Worked on the ickshonpe/bevy repository to enhance UI layout flexibility by introducing the ValNum trait, enabling Val-helper functions to accept various numeric types and convert them seamlessly to f32 for UI dimension calculations. This approach leveraged Rust’s macro system to implement the trait across common numeric types, reducing repetitive code and minimizing potential errors in UI development. The work focused on improving the reliability and maintainability of UI layouts by supporting flexible numeric input, making it easier for developers to experiment with layout parameters. Core skills applied included Rust, macro usage, trait implementation, and UI development within the project context.
