pub struct LzssDecoder { /* private fields */ }

LZSS sliding window decoder.

Implementations

impl LzssDecoder

pub fn new(window_size: usize) -> Self

Create a new LZSS decoder with the specified window size.

pub fn rar29() -> Self

Create decoder for RAR 2.9 format.

pub fn rar50() -> Self

Create decoder for RAR 5.0 format.

pub fn write_literal(&mut self, byte: u8)

Write a literal byte to the output.

pub fn copy_match(&mut self, distance: u32, length: u32) -> Result<()>

Copy bytes from a previous position in the window.

pub fn position(&self) -> usize

Get the current window position.

pub fn total_written(&self) -> u64

Get total bytes written.

pub fn get_byte_at_offset(&self, offset: usize) -> u8

Get a byte at the specified offset from current position (going back).

pub fn get_output(&self, start: u64, len: usize) -> Vec<u8>

Extract decompressed data from the window. Call this after decompression to get the output.

pub fn get_recent(&self, len: usize) -> Vec<u8>

Get the most recent len bytes from the window.

pub fn reset(&mut self)

Reset the decoder state.
