I think its really interesting such gems offering a ruby layer on top of rust libs. One issue that I have with that is - and maybe it's my ignorance - but is that necessary to bundle the original lib as <a href="https://github.com/ankane/polars-ruby/tree/master/ext/polars">https://github.com/ankane/polars-ruby/tree/master/ext/polars</a> ? I can imagine that makes easier to avoid breakage, or with C extensions, because you dont have some dependency manager around, but couldn't we sort it with Cargo? For instance, having the version locked and it could download (and cache) the dependency when necessary?
