How is your experience with using C++ libraries in Rust?

• rust-bindgen

  50 4,131 9.0 Rust

  Automatically generates Rust FFI bindings to C (and some C++) libraries.

  

I tried using a C++ library using bindgen, and while it worked the generated Rust bindings where HUGE and included a ton of things from the C++ stdlib (isn't header files just a wonderful concept...). So instead I wrapped the C++ code in a small C library with a minimal API (basically just depending on stdint.h). That produced minimal Rust bindings and integrates with Rust very well (except for C strings which are a PITA), I think it was worth the extra hours spent.

• cxx

  97 5,527 9.3 Rust

  Safe interop between Rust and C++

A while ago I started integrating a C++ project using cxx. However, cxx was not straightforward to set up at the time, and the project had a mostly "C with classes" code style. So eventually I used bindgen, by creating my own C API. Nowadays, to work with a modern C++ API, I'd definitely give cxx another try.
