Building PyO3/Maturin Rust Extension Modules as WebAssembly Wheels for Pyodide
— Compiling Rust-based Python extension modules (via PyO3 and maturin) into WebAssembly wheels for Pyodide involves precise coordination of toolchain versions and build flags to ensure compatibility. The process relies on maturin (≥1.0) for packaging, the Emscripten SDK (with the exact version used by Pyodide), and a Rust nightly toolchain matching Pyodide's ABI, particularly the `-Z emscripten-wasm-eh` flag and a compatible sysroot for Python 3.13 (Pyodide 0.28+).
