    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 https://github.com/ankane/polars-ruby/tree/master/ext/polars ? 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?

    ankane’s gems are truly something.

    polars is a really great library. Cool to see it expanding into so many languages too.

    I'm trying to imagine why somebody would start a data analytics project in ruby.
