Zngur: A C++/Rust interop tool

I've been learning Rust and really enjoying it, but the primary downside (compared to C++) is the lack of access to the large, well-tested libraries that exist in C++. For example, my work would benefit from using the CGAL library [0], something that be nontrivial to rewrite in Rust. As much as I like Rust, at some point it's a better idea to use C++ to tap into libraries like that.

Does anyone have thoughts about how mature Zngur/CXX/etc. are for a project like mine? Would it be reasonable to invest effort in creating those bindings? Thanks.

   So, Zngur allows you to use arbitrary Rust types in C++, store them by value in the C++ stack, and call arbitrary Rust methods and functions on them. But it doesn't bridge any C++ type into Rust, since it is not possible with the same ergonomic

You want to use C++ libraries from Rust. This only does interop the other way.

I’m using cxx/cxx-qt in a Rust QT app with substantial interop with Qt/QML and lots of C++ code (because Gpt/Claude make implementing some stuff easier in C++). It’s definitely mature enough because Qt’s libs are no joke.

At this point I have a Claude project set up with Cxx documentation and it autogenerates most of my bindings.

Wow! Amazing how reframing the problem to exclude C++ types in rust makes it all so much more elegant.

I've used cxx.rs to bind to the OpenCascade CAD kernel. It was a lot of work but the bindings seem to work well.

Do you have some specific usage of Claude to help? Or how do you use Claude/Gpt for this more precisely?
