Rust can go low-level, but its succintness (compared to C) is when dealing with high-level structures. Things like vectors, hashmaps, or even strings. Those rarely are use on a driver.
In addition to that: in C you can share a pointer in many places and write memory wherever you want. Since rust has ownership system things get a little more complicated. Sometimes you have to write extra code to appease the borrow checker.
Consider that you will never get the situations you get in C, where forgetting to check for NULL in one place can result in privilege escalations (example: https://www.exploit-db.com/exploits/33322/). I think it's worth it.
