  1. There's a huge push for this from the big companies adopting Rust. Google has been developing https://github.com/google/crubit . The older cbdingen is still usable if more limited (it's what Firefox uses for some pretty involved interop).

  2. In the long run https://github.com/google/crubit will very likely solve this for Rust even if it's a bit specific to Google's use cases right now as per readme.

  5. I think they had another such effort for a while here: https://github.com/google/crubit

  6. What I'm really hoping is that https://github.com/google/crubit eventually gets good enough to facilitate incremental migration of brownfield C++ codebases to Rust. That seems like it would address this concern.

  11. …) and ongoing research into automating this interoperability ( https://github.com/google/autocxx , https://github.com/google/crubit ). Feels like there's enough effort in all areas. I don't understand a request that says "drop everything…

  12. …Rust can interop with C++ with high fidelity. For example https://docs.rs/moveit/latest/moveit/ and https://github.com/google/crubit/blob/main/rs_bindings_from_... provide functionality to use non-trivially relocatable C++ types from Rust.

  13. …docs (can't remember where) is a link to a Rust/C++ interop project sponsored by Google, Crubit: https://github.com/google/crubit/blob/main/docs/design.md In case it's not clear, Carbon is also at the moment a Google project. There's not…
