Performance? Not really no. I believe C is slightly faster with Rust and C++ competing for second place. The benefit is safer code as Rust is built with performance and safety in mind. It highlights what potential errors can be found where making human error way less common. Instead of potential null errors types are wrapped in an option enumerator which ensures you know there can be a lack of a value. Expections are also enumerators done similarly with a result object so you know which functions may fail. Instead of using memory and potentially forgetting to free it we have the ownership system.

How is C faster than C++? Unless you use virtual functions, it’s as performant as C. And you definitely wouldn’t use virtual functions in a kernel.
