Struct VlcTable 

pub struct VlcTable { /* private fields */ }

Flat decode table built from Huffman codes.

Implementations

impl VlcTable

pub fn build(codes: &[(u32, u8, i32)], max_bits: u8) -> Self

Build from (code_bits, code_len, symbol) triples.

pub fn decode(&self, br: &mut BitReader<'_>) -> Option<i32>

Decode one symbol. Advances the reader by the code length.

pub fn max_bits(&self) -> u8

pub fn max_level(&self, run: usize, last: bool) -> u8

Max level coded for given (run, last) in this table.

pub fn max_run(&self, level: usize, last: bool) -> u8

Max run coded for given (level, last) in this table.
