//! Python bindings for preprocessing transformers
//!
//! This module provides Python bindings for sklears preprocessing,
//! offering scikit-learn compatible data transformation utilities.
//! Each transformer type is implemented in its own submodule for
//! better code organization.
// Common functionality shared across preprocessing transformers (internal use only)
// Individual transformer implementations
// Re-export all transformer classes for PyO3
