Struct Encoder 

pub struct Encoder {
    pub low: u64,
    pub range: u32,
    /* private fields */
}

The binary range encoder.

Fields

low: u64

The low bound of the current interval.

range: u32

The size of the current interval.

Implementations

impl Encoder

pub const TOP_VALUE: u32

The value above which the range is renormalised.

pub fn new() -> Self

Creates an uninitialised encoder.

pub fn set_stream(&mut self, stream: Vec<u8>)

Replaces the output buffer.

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

Takes the output buffer out of the encoder.

pub fn stream(&self) -> &[u8]

The bytes written so far.

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

The bytes written so far, mutably.

pub fn init(&mut self)

Initialises the encoder for a new stream.

pub fn flush_data(&mut self)

Flushes the pending low bytes.

pub fn flush_stream(&mut self)

Flushes the output stream.

Does nothing, since a Vec<u8> has nothing to flush.

pub fn close_stream(&mut self)

Closes the output stream.

Drops the output buffer.

pub fn encode(&mut self, start: u32, size: u32, total: u32)

Encodes a symbol that occupies size of total probability units.

pub fn shift_low(&mut self)

Shifts the low accumulator by one byte, emitting the pending bytes.

pub fn encode_direct_bits(&mut self, v: u32, num_total_bits: i32)

Encodes num_total_bits bits of v without a probability model.

pub fn encode_bit(&mut self, size0: u32, num_total_bits: i32, symbol: u32)

Encodes a single bit using a probability model of num_total_bits bits.

pub fn get_processed_size_add(&self) -> i64

The number of bytes produced so far, plus the four bytes that the decoder needs to finish the stream.

Trait Implementations

impl Clone for Encoder

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Encoder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Encoder

fn default() -> Self

Returns the “default value” for a type.
