rust-cpp VS bitflags

I am the current passive maintainer of the cpp crate: https://github.com/mystor/rust-cpp

I would like to utilize OMPL's functionality in Rust code, so I want to call into OMPL C++ code somehow in Rust. I've seen two (non-mutually-exclusive) options so far: - rust-cpp, which allows you to write C++ code in Rust within the cpp!() macro. - cxx, which allows you to define both sides of the FFI boundary manually (as opposed to bindgen's automatic generation).

There's also the cpp and cxx crates for doing C++/Rust interop, but they probably aren't appropriate to use in all cases. The C ABI is definitely the safest way to go unless you're really trying to marry Rust and C++ code bases, not just writing library bindings.

https://github.com/mystor/rust-cpp <- not a transpiler, but almost as good

Otherwise, C would never have achieved success in MS-DOS when all the stuff it was binding to at the time required blocks of inline assembly. (Crates like rust-cpp do exist, which allow "inline C++" in the same way that C++ allows inline assembly.)

Actually, you can make inline C++ macro in Rust. Similar unholy monstrosities exist for inline python, inline C, inline SQL, inline HTML,...

Here is a more serious project that allows to embed C++ code directly in your Rust code: https://github.com/mystor/rust-cpp

Don't underestimate the power of procedural macros: https://github.com/mystor/rust-cpp

Alright, thanks for all your ideas! I also found this mystor/rust-cpp, which apparently allows inline c++ as opposed to cxx. Having yet to try out any of these, I like the idea of inline code more. Thought now I feel I need to brush up my skills a bit more to try this stuff out.

I’m collecting input in this issue if there’s anything you’d like to see done. I’m keen to hear about any burning issues you’ve run into!
