Worked on a major upgrade of the WebSocket stack in the tokio-rs/axum repository, focusing on enhancing reliability and preparing the codebase for future real-time features. The work involved upgrading the tokio-tungstenite dependency to version 0.26.0 across multiple axum crates and updating Cargo.toml constraints to streamline future maintenance. Adjustments were made to WebSocket text message handling to support Utf8Bytes, ensuring compatibility with upstream changes and preventing regressions. The project emphasized dependency management, Rust programming, and WebSockets, delivering immediate business value by improving stability and reducing friction for future upgrades without introducing new bugs during the process.
