The answer to your question is in most if not all arguments against the widespread use of C/C++ in something as high level as OpenSSL. C and C++ ask a lot of developers, mostly in terms of ensuring memory safety. It’s possible to write crappy code in Rust, sure, but the language design has taken the decades of experience of knowing where C falls short and provides a more safe natural path. The long-running rebuttal to this is “it’s as easy as using function x instead of function y!” with the name of function x being some inscrutable derivative of the name of function y. If it’s so easy, why do C codebases keep having the same issues? I’d seriously question the software development experience of someone that doesn’t see the value in reducing developer cognitive load.
