No. A ton of languages don’t support proper Sum Types, and Rust’s emphasis on errors-as-values helps you think about error handling, instead of only thinking about the happy path. Rust also doesn’t do implicit type coercion and a host of other things that can cause correctness issues. Rust gives you the tools to express more of what you’re doing to the compiler than a lot of languages, which lets the compiler help you more. It’s natural that a lot of programs have some form of concurrency, so that’s an extremely common thing for Rust to help with, but it’s not the only thing.
