If you want assembler Rust seems like a smarter choice because in Rust that's just part of the language whereas in C or C++ it's a vendor extension.

Assembly is never really part of the language, at most one could consider the syntax to inject a stream of opcodes being part of the language.

Both of us are old enough to remember when any useful compiled language used to allow for inline Assembly, extension or not.
