Python cryptography, Rust, and Gentoo

No they won't.

Rust is designed to eliminate "undefined" or "implementation defined" behavior outside of explicit "unsafe" blocks. Yes, there will be compiler bugs etc, but really there will be vastly less of such problematic behaviors in Rust programs than in C and C++ programs.

That means we can expect Rust programs to behave much more consistently over time than C/C++ programs, as hardware and compilers evolve.
