Hey all,

Great work here. Just to experiment with Rust and extendr (a rust framework for R/Rust integration), I started to map SingleRust utilities to R functions here: https://github.com/Artur-man/RSingleRust

Currently, I am trying to see how one can pass updates to polars/_core::frame::DataFrame to an R object. I discussed this with extendr developers and they developed gateways for that
https://github.com/extendr/arrow-extendr?tab=readme-ov-file#polars-interop

Here is where the conversion supposed to happen:
https://github.com/Artur-man/RSingleRust/blob/2d792093d6d0a70d5c2209c7d71800c833b208c5/src/rust/src/lib.rs#L126

However, singlerust and anndata-memory depends on polars/_core 0.51.0 but arrow_extendr on 0.53.0 which results in a crash when I attempt obs_df.into_arrow_rob(...). How restricted are you guys are to v51 or would it be possible to bump the dependency ?

Here is more about extendr: https://extendr.rs/
