The reason that I&#x27;m using Rust and Node together is Lambda. It supports Java, Python and Node and my (admittedly perfunctory) tests showed that Node had the smallest overhead of the three in getting to Rust. However, this library seems to offer a richer interaction between the two platforms, which would imply using Node as something beyond a bridge to Rust, so there&#x27;s likely an answer beyond mine that the author has in mind.
