Worked on the OpenDevicePartnership/embedded-services repository to enhance the Power Button service by introducing equality support for the Message enum in Rust. This addition involved implementing the PartialEq and Eq traits within button_interpreter.rs, enabling direct comparison of Message variants. The change improved testability and streamlined state management for embedded systems, allowing for more efficient test-driven development and reducing debugging time. By focusing on minimal yet targeted code modifications, the work laid a foundation for scalable stateful testing and broader coverage of the power button workflow. The project leveraged expertise in Rust and embedded systems to deliver maintainable, test-friendly code.
