Depends on 6 packages(full list with versions):

base, containers, primitive, random, text, vector

Used by 13 packages in nightly-2026-08-30(full list with versions):

dataframe, dataframe-csv, dataframe-expr-serializer, dataframe-fastcsv, dataframe-json, dataframe-lazy, dataframe-learn, dataframe-operations, dataframe-parquet, dataframe-parquet-th, dataframe-parsing, dataframe-th, dataframe-viz

Minimal interchange-format types for the dataframe ecosystem: Column, DataFrame, Bitmap, the untyped expression/interpreter, and the typed-schema phantom layer. Contains no Template Haskell and no file I/O. Lightweight dependency footprint (base, vector, containers, time, random, bytestring, text) so other packages can exchange dataframes by-value without pulling in the full dataframe package.
