As someone who has dived into Rust over the past few months, the two main reasons for employing it are: A) Bleeding edge performance (Shares the same problem space as C/C++, zero cost abstractions etc.) B) Memory safety (Giving it a rather unique flavour among systems languages - distinguishing it from the above two)

If you primarily work in C#, the latter won't be a problem you will be looking to solve anyway. I would say if the former intrigues you then Rust would be a great place to start.
