Struct SymbolReader 

pub struct SymbolReader { /* private fields */ }

High-level symbol reader for CDF-based arithmetic coding.

Implementations

impl SymbolReader

pub fn new(data: Vec<u8>) -> Self

Create a new symbol reader.

pub fn read_symbol(&mut self, cdf: &mut [u16]) -> usize

Read a symbol using a CDF.

Updates the CDF after reading.

pub fn read_symbol_no_update(&mut self, cdf: &[u16]) -> usize

Read a symbol without updating CDF.

pub fn read_bool(&mut self, cdf: &mut [u16; 3]) -> bool

Read a boolean value using a CDF.

pub fn read_bool_eq(&mut self) -> bool

Read a boolean with fixed probability (128/256).

pub fn read_literal(&mut self, n: u8) -> u32

Read a literal (fixed-length code) of n bits.

pub fn read_subexp(&mut self, k: u8, max_val: u32) -> u32

Read an unsigned value using subexp coding.

pub fn read_signed_subexp(&mut self, k: u8, max_val: u32) -> i32

pub fn read_inv_recenter(&mut self, r: u32, max_val: u32) -> u32

Read inverse recenter value.

pub fn read_ns(&mut self, n: u32) -> u32

Read NS (non-symmetric) coded value.

pub fn has_more_data(&self) -> bool

Check if more data is available.

pub fn position(&self) -> usize

Get current byte position.

pub fn remaining(&self) -> usize

Get remaining bytes.
