Struct BitEncoder 

pub struct BitEncoder { /* private fields */ }

A single binary probability model.

Implementations

impl BitEncoder

pub const NUM_BIT_MODEL_TOTAL_BITS: i32 = 11

The number of bits used to represent a probability.

pub const BIT_MODEL_TOTAL: u32

The total number of probability units.

pub const NUM_MOVE_BITS: i32 = 5

The number of bits the probability is shifted by on every update.

pub const NUM_MOVE_REDUCING_BITS: i32 = 2

The number of bits the probability is reduced by when pricing.

pub const NUM_BIT_PRICE_SHIFT_BITS: i32 = 6

The shift applied to the price of a bit.

pub fn new() -> Self

Creates an uninitialised model (probability zero).

pub fn init(&mut self)

Resets the probability to its initial value.

pub fn prob(&self) -> u32

The current probability.

pub fn update_model(&mut self, symbol: u32)

Updates the probability for the given symbol.

pub fn encode(&mut self, encoder: &mut Encoder, symbol: u32)

Encodes one bit with this model and updates it.

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

The price of encoding symbol.

pub fn get_price0(&self) -> u32

The price of encoding a zero bit.

pub fn get_price1(&self) -> u32

The price of encoding a one bit.
