//! Huffman coding module.
//!
//! This module contains Huffman table types, encoding, and optimization:
//! - `encode`: Huffman encoding functions and tables
//! - `classic`: Optimal Huffman table generation (mozjpeg-style algorithms)
//! - `types`: Additional Huffman types and comparisons
//! - `optimize`: Two-pass Huffman optimization with frequency counting and clustering
//! - `trained`: Pre-trained Huffman tables for streaming encoding

pub mod classic;
pub mod encode;
pub mod optimize;
