netcode

+1 to everything said here. It really is very straightforward to start inserting Rust into a C/C++ codebase. I did the Rust port of netcode.io[1] which started out by just calling C code for the portions that I didn't have working in Rust. Eventually the port was 100% Rust but I was really impressed with how seamless mixing C/Rust was. Even now our unit tests run against the C code at a functional level so we know when the protocol diverges which lets us easily catch breaking changes from the reference C implementation. Much like everything, don't apply an adage blindly and do a proper evaluation but I think if you're in the a space where memory or performance matters Rust is a very strong contender that plays well with existing ecosystems.
