symbol_tt: Vec<SymbolTT>

max_symbol: usize

Implementations

impl FseCTable

pub fn build(norm: &[i16], max_symbol: usize, table_log: u32) -> Self

Build an FSE compression table from normalized counts. Ported from FSE_buildCTable_wksp() in fse_compress.c.

pub fn build_rle(symbol: u8) -> Self

Build an RLE compression table: single symbol, 0 bits per encode. init_state returns 0, encode_symbol always returns (0, 0, 0). table_log = 0, matching the decoder’s RLE behavior.

pub fn init_state(&self, symbol: usize) -> u32

Initialize FSE state for the first symbol (FSE_initCState2).

pub fn encode_symbol(&self, state: u32, symbol: usize) -> (u32, u32, u32)

Encode a symbol: output bits from current state, then transition. Returns (bits_to_output, nb_bits, new_state).
