I can only speak for myself, obviously. But, I think it's obviously about more than performance. Otherwise, people have always had C, C++, LISP, and even Java and Go that will be generally faster than Python, PHP, and JavaScript. I'd say there are three things that most people rave about with Rust: * traits as type classes (even if they don't know the term "type class") * enums and pattern matching (not even as flexible as some other languages like MLs, but way more than is possible in most popular languages with only Swift coming close) * the Iterator trait. I might write a sonnet about how much I love Iterator in Rust. It's lazy iteration, but it's also optimized at compile time to basically just be turned into a for loop.
