Struct arcode::model::Model

pub struct Model { /* private fields */ }

Symbol table for the encoder/decoder. Used to store the probabilities as a vector of counts (number of occurrences). Uniform would be every symbol has a count of 0.

Implementations

impl Model

pub fn builder() -> Builder

pub fn from_values(
    counts: Vec<u32>,
    fenwick_counts: Vec<u32>,
    total_count: u32,
    eof: u32
) -> Self

For loading a saved model. Use the Builder for more options.

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

pub const fn num_symbols(&self) -> u32

pub fn high(&self, index: u32) -> f64

pub fn low(&self, index: u32) -> f64

pub fn probability(&self, symbol: u32) -> (f64, f64)

pub const fn eof(&self) -> u32

pub const fn counts(&self) -> &Vec<u32>

pub const fn fenwick_counts(&self) -> &Vec<u32>

pub const fn total_count(&self) -> u32
