Do you know its not easy to decide whether you're trolling or not ? > Did we really need to work in deep with Rust if we write just a Rust wrapper?
Maybe not but... You said you're not a Nim user. Can you wrap a C library into Nim ? without knowing any of them ? Whoever wraps a Rust library must know both, Nim and Rust, at least at medium level. Besides, its not enough. Users of that wrapper will probably have to know Rust too if they ever need to peek inner workings of library, if they hit some bug in the library etc.
