PandRS 0.3.1 Released — Pure Rust Excel I/O Backed by OxiARC, Zero C Compression Libs
High-performance DataFrame library for Rust — pandas-class API with SIMD, parallel, and distributed processing. 0.3.1 swaps the Excel/xlsx C-dependency chain (zip/flate2/miniz_oxide via calamine + simple_excel_writer) for an in-tree OxiARC-backed xlsx engine, removes the dirs -sys crate, and pins datafusion/parquet/arrow to drop liblzma/zstd-sys/lz4-sys. 1809 tests + 117 doc tests passing, zero clippy warnings. The DataFrame layer of the COOLJAPAN scientific stack.
