I thought @arnetheduck's response was the mic drop; there's no reason Nim can't use Rust (or C, C++, or JS ...) libraries. If the OP wants Nim bindings over Rust, they can write them.
If the question is rather, 'why doesn't someone else do what I want', that has many answers. As a Rust fan (and someone who has been paid to write Rust) let me say that I'd rather see more **pure** Nim libraries, **especially** for things Rust is arguably good/better at. I want to see the Nim design pushed hard in many directions, and "low level systems programming" is one of the important directions, scientific computing being another.
