Trait CodebookDescReader

pub trait CodebookDescReader<S> {
    // Required methods
    fn bits(&self, idx: usize) -> u8;
    fn code(&self, idx: usize) -> u32;
    fn sym(&self, idx: usize) -> S;

This trait defines a series of methods to get some information from a codebook.

Required Methods

fn bits(&self, idx: usize) -> u8

Returns the codeword length for the provided index.

fn code(&self, idx: usize) -> u32

Returns the codeword bits for the provided index.

fn sym(&self, idx: usize) -> S

Returns the codeword value (codeword symbol) for the provided index.

fn len(&self) -> usize

Returns the total number of defined codewords.

fn is_empty(&self) -> bool

Tells if the codebook is empty or not.
