rumo

rumo is a Rust library that reads and describes Polars DataFrames. It ships with a CLI binary and Python bindings.

CLI usage

Run against any CSV file:

cargo run --bin rumo -- --file examples/sample.csv

Example output:

DataFrame: 5 rows × 3 columns
  - name (str)
  - age (i64)
  - score (f64)

Python usage

Build and install the Python extension locally:

maturin develop --features python

Then use it from Python:

import polars as pl
import rumo

df = pl.read_csv("examples/sample.csv")
print(rumo.describe(df))

See examples/describe_dataframe.py for a runnable example.
