//! 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.
