Struct BitTreeEncoder 

pub struct BitTreeEncoder { /* private fields */ }

A tree of binary probability models, addressed by the bits of a symbol.

Implementations

impl BitTreeEncoder

pub fn new(num_bit_levels: u32) -> Self

Creates a tree with num_bit_levels levels.

pub fn num_bit_levels(&self) -> u32

The number of levels of the tree.

pub fn init(&mut self)

Resets every model of the tree.

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

Encodes a symbol, most significant bit first.

pub fn reverse_encode(&mut self, range_encoder: &mut Encoder, symbol: u32)

Encodes a symbol, least significant bit first.

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

The price of encoding a symbol, most significant bit first.

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

The price of encoding a symbol, least significant bit first.

pub fn reverse_get_price_at( models: &[BitEncoder], start_index: u32, num_bit_levels: i32, symbol: u32, ) -> u32

The price of encoding a symbol with an external tree, least significant bit first.

pub fn reverse_encode_at( models: &mut [BitEncoder], start_index: u32, range_encoder: &mut Encoder, num_bit_levels: i32, symbol: u32, )

Encodes a symbol with an external tree, least significant bit first.
