    /* private fields */

Fields

state: Entry

An FSE state value represents an index in the FSE table.

Implementations

impl<'t> FSEDecoder<'t>

pub fn new(table: &'t FSETable) -> FSEDecoder<'_>

Initialize a new Finite State Entropy decoder.

pub fn decode_symbol(&self) -> u8

Returns the byte associated with the symbol the internal cursor is pointing at.

pub fn init_state( &mut self, bits: &mut BitReaderReversed<'_> ) -> Result<(), FSEDecoderError>

Initialize internal state and prepare for decoding. After this, decode_symbol can be called to read the first symbol and update_state can be called to prepare to read the next symbol.

pub fn update_state(&mut self, bits: &mut BitReaderReversed<'_>)

Advance the internal state to decode the next symbol in the bitstream.
