The language is an implementation detail; what makes you think Rust would be better suited for such a specialist piece of software?

It's a joke, as some Rust projects used to repetitively claim to be "memory safe & blazing fast", thus becoming a tongue-in-cheek phrase. I also anticipated language to be Rust, but it would be way too comical.

I’ll admit, I went into their repo expecting to find Rust, or at the very least go. Pleasantly surprised to see C++ code though I would need to look further to see if it’s “good” C++ code. The naming conventions of the source tree lends me to suspect it’s not.

i too determine if code is good based off its naming conventions and other things like my linter is set to enforce MiXeD_SpOnGeBoB-KeBaB_CaSe as the default casing

Better than p_f_var_t;
