Polars: Racket bindings to Polars🔗ℹ

polars provides Racket bindings to the Polars DataFrame library. The bindings call into a native compatibility library (libcompat) built from the Rust polars crate; prebuilt shared objects for Linux (x86-64) and macOS (arm64) ship with the package and are installed automatically, so no Rust toolchain is required at install time.

The polars module re-exports three groups of operations:

• Series — typed, one-dimensional columns of data.

• Expressions — composable, lazily-evaluated column expressions used to describe transformations.

• DataFrames and LazyFrames — tabular data and the lazy query plans that produce it.

Temporal values exchanged with Racket use gregor dates and datetimes.

This manual has two parts. The Guide is a guided, narrative tour modelled on the upstream Polars getting-started guide; the Reference documents the public API.
