Rust isn't the only alternative to write native code safer than C will ever allow.
On the downside, if you want to call it that, is a more prominent syntax (keywords instead of curlies, upper-case keywords, etc).
On the upside it lacks any unsafe operations, except for dealloc. In addition, it has actual modules in lieu of includes, hence it's blazingly fast to compile and/or recompile. It'a a pity it didn't catch on, the language lacked a company to back and promote it. AT&T promoted C, Apple promoted Objective C, Microsoft promoted VB...
Actually Apple promoted Object Pascal, but then they decided to cater to the growing UNIX market and replaced the Mac OS SDK with C and C++ (PowerPlant) one.
Ada was and still is a quite modern language, designed for software development done by large teams, where I can several years later still understand what I wrote.
