There's also a more blasphemy-ish approach of interop between C++ and Rust if the C++ code already have good Python bindings: C++ <=> Python <=> Rust. It's not bad as you may think. My company uses it to adapt C++ to Rust without rewriting the 40K LOC Pybind11 boilerplate. Going through the Python interpreter is definitely slower than a native call but perhaps <3x since we only rely on Python being a hosted + GC environment, plus it's much easier to express lifetime in Rust given that everything is managed on Python heap.
