Crate alopex_dataframe 

alopex-dataframe is a small, Polars-inspired DataFrame API built on Arrow.

The v0.1 scope focuses on a minimal eager DataFrame and a lazy query pipeline (LazyFrame) that compiles logical plans into physical plans and executes them. CSV / Parquet I/O is provided via arrow-csv and parquet.
