    If you’re going to claim that something is fast or so, have some numbers to back it up. Also define what you mean by ‘fast’.

      apart from anything else, this is from 2013. also the rust team has been quite explicit about getting the safety aspects right first; they definitely want the language to be fast, but it’s easier to optimise for speed than to retrofit more fundamental features.

      if you want a language that is fast and safe right now, albeit a lot harder to use than rust is, give ATS a look.
