During February 2026, Lizan contributed to the rust-lang/rust repository by addressing a compile error in the WebAssembly unwind module. Focusing on system programming with Rust and WebAssembly, Lizan resolved the issue by wrapping the wasm_throw call in an unsafe block, carefully adhering to Rust’s safety guarantees while enabling proper exception handling in the unwind path. This targeted use of unsafe code established an explicit safety contract, improving build stability and reducing CI failures for wasm-related workflows. The work demonstrated a thoughtful approach to managing Rust’s safety model in performance-critical code, reflecting a solid understanding of both language features and system reliability.
