What does Rust's compiler tell you that C#'s doesn't? You still have guaranteed memory safety in C#, and the type checker will verify against all type errors.

What does Rust's compiler tell you that C#'s doesn't? You still have guaranteed memory safety in C#, and the type checker will verify against all type errors. I realize that Rust's compiler might catch more concurrency problems, but your comment is written as if you feel "blind" even writing single threaded code.

Rust's match is a lot more powerful than C#'s third party OneOf type alone

Rust's advantages don't stop at concurrency or type safety. In my experience, the type system is actually much more concise and the APIs are a lot more explicit than any other language I've tried. It's clear when the argument you're passing is going to be mutated or not and move semantics help a lot on designing good APIs (not having to remember to close a File or being able to use it after it's closed, for example). Not to mention sum types with pattern matching, being expression based, etc. I also find that Structs and Enums being values instead of references (as opposed to Classes in other languages), reasoning about the code is a lot more straightforward, which goes back to my point about explicit mutability. A huge part of it also goes to great libraries created by the community, that usually cares about API soundness. It's very common in Rust to do a big refactor or write a program from scratch and have it work on the first or second try, which may release a good amount of dopamine for some.[0] Not saying the language is perfect, but it can feel pretty good, to the point of being addictive, while also freeing to know you can think less about the variants and let the compiler do it for you, and the reliability of the created program is usually pretty amazing. It can also be annoying, specially when you're learning it and try doing something in a way that's just not viable in an easy way (e.g. manually creating a Linked List).
