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.
High-performance pure Rust DataFrame library — a pandas-class API with SIMD, parallel processing, and distributed compute. 0.3.0 purges the entire SQL/database stack (sqlx, rusqlite, libsqlite3-sys) to enforce Pure Rust, modernizes the columnar engine to Arrow/Parquet 58.1 and DataFusion 53.0, and upgrades SciRS2 integration to 0.4.0. The DataFrame layer of the COOLJAPAN scientific stack, alongside NumRS2.
