Struct Huffman 

pub struct Huffman { /* private fields */ }

Huffman codec for RuneScape chat messages.

Builds a canonical Huffman code from a bit-length table (one byte per symbol, typically 256 entries loaded from the cache). Provides encode/decode for raw byte buffers — string handling is left to the caller.

Implementations

impl Huffman

pub fn new(bit_lengths: &[u8]) -> Self

Build the codec from a bit-length table.

pub fn encode(&self, src: &[u8], dest: &mut [u8]) -> usize

Encode src into Huffman-compressed bytes in dest. Returns the number of bytes written.

pub fn decode( &self, src: &[u8], src_off: usize, dest: &mut [u8], len: usize, ) -> usize

Decode len symbols from Huffman-compressed src[src_off..] into dest. Returns the number of source bytes consumed.
