Crate re_arrow_combinators 

Type-safe, composable transformations for Arrow arrays.

This crate provides composable transformations for Arrow arrays. Transformations are composable operations that convert one array type to another, preserving structural properties like row counts and null handling.

These transformations serve as building blocks for user-defined functions (UDFs) in query engines like DataFusion, as well as SDK features like lenses.
