There is an effort to automate generating mid-level C bindings for C++ code automagically, to enable easier wrapping in high level Rust APIs, by an unofficial Academy [of Motion Pictures] Software Foundation group. It is called C++-- [1].

At this time we only target the VFX C++ ecosystem but I'd be surprised if people wouldn't use (and extend) this to cover a broader set of C++ libs.

Maybe you can give an example of a C++ API that you deem not "translatable to C"?

For example, OpenVDB uses templates with user provided arguments at the very heart of its tree structure. Similar things happen in PCL and CGAL. They are template-heavy libraries by design.

OpenCV on the other hand seems to instantiate all possible variants of cv::Mat for their Python bindings. They don't such a big space of valid and useful template parameters and IIRC the specifics are abstracted away from the algorithms working on them.

That's kind of hilarious given the role that C++ to C compiler had in the early development of the language [1]. But sounds useful, thanks for the link.

There is also this, [1], which wasn't on my radar until today:

"Corrosion, formerly known as cmake-cargo, is a tool for integrating Rust into an existing CMake project. Corrosion is capable of importing executables, static libraries, and dynamic libraries from a crate."
