We could add support for Rust, and it would work the same as go, do a built step prior, and then cache the binary. If we have enough demand for it, we will add it (we are a small team and can only prioritize what's popular unfortunately).

On a personal note, I write a lot of rust (and love it) but using rust for writing non-backend type of stuff is not something I would do myself. I'm more of a believer of hybrid like polars that optimize the compute in Rust but provide a compatible sdk in python.
