While I love Nim, another reason for Rust's success (aside from its type system, general good language design, and zero-cost memory safety) is that the tooling is ridiculously good, probably the best of any language I've used, sans maybe Java. Nim's tooling is improving but still has a ways to go - I still occasionally get orphaned langserver processes, and while the langserver itself is pretty good, it's nowhere near the level of what rust-analyzer can do. Especially with error messages and (automatic) refactoring.
