• Use emsdk 2.0.13.
• cargo +nightly run --target wasm32-unknown-emscripten should work but currently fails. Instead copy the failing command and:
  • Remove "-l" "c"
  • Replace "-s" "ERROR_ON_UNDEFINED_SYMBOLS=1" with ...=0
  • Run it manually in the console.
  • Invoke node --experimental-wasm-threads --experimental-wasm-bulk-memory target/wasm32-unknown-emscripten/debug/deps/emscripten_rust_test.js (Cargo would've put it a bit further up and could execute it manually, but since it failed early in the process, we have to get a temporary artifact instead).
