Implementations

impl RangeCoder

pub fn new_encoder(size: u32) -> Self

pub fn reset_for_encode(&mut self, size: u32)

pub fn new_decoder(data: &[u8]) -> Self

pub fn enc_uint(&mut self, fl: u32, ft: u32)

pub fn dec_uint(&mut self, ft: u32) -> u32

pub fn enc_bits(&mut self, val: u32, bits: u32)

pub fn pad_to_bits(&mut self, target_bits: i32)

pub fn dec_bits(&mut self, bits: u32) -> u32

pub fn tell_frac(&self) -> i32

pub fn tell(&self) -> i32

Integer bit count matching C’s ec_tell(): nbits_total - EC_ILOG(rng).

pub fn tell_fast(&self) -> i32

pub fn shrink(&mut self, new_size: u32)

Shrink the range coder buffer, moving end-coded bytes to the new end. Equivalent to C’s ec_enc_shrink.

pub fn decode(&mut self, ft: u32) -> u32

pub fn update(&mut self, fl: u32, fh: u32, ft: u32)

pub fn laplace_encode(&mut self, value: &mut i32, fs: u32, decay: i32)

pub fn laplace_decode(&mut self, fs: u32, decay: i32) -> i32

pub fn patch_initial_bits(&mut self, val: u32, nbits: u32)

pub fn done(&mut self)

pub fn finish(&mut self) -> Vec<u8>

Trait Implementations

impl Clone for RangeCoder

fn clone(&self) -> RangeCoder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
