It's that, plus a number of other things: - Rust is low-level enough to write sanakirja, which is pijul's database backend, in a clean way, without having to decode/re-encode tons of things from disk all the time. - Types! A sane (as in "mathematically sound") type system. That sentence is easy to misinterpret if you've not written actual programs (of more than ten lines) in functionnal programming, but types are essential for a program several dozens of thousands of lines long, in total. It basically means that we could refactor our code many times without fear. - Rust's community is awesome. I had never seen anything like that before. - Support for threads, both low-level and easy. That said, Turing-complete programming languages won't prevent anyone from doing stupid things, by definition. I'm not sure about the particular focus on parsing: non-parsing tasks also required a bit of thinking.
