Struct compress::entropy::ari::table::ByteDecoder

pub struct ByteDecoder<R> {
    pub decoder: Decoder<R>,
    pub freq: Model,
    // some fields omitted
}

A basic byte-decoding arithmetic expects a special terminator code for the end of the stream

Fields

decoder: Decoder<R>

A lower level decoder

freq: Model

A basic frequency table

Implementations

impl<R: Read> ByteDecoder<R>

pub fn new(r: R) -> ByteDecoder<R>

Create a decoder on top of a given Reader

pub fn finish(self) -> (R, Result<()>)

Finish decoding

Trait Implementations

impl<R: Read> Read for ByteDecoder<R>

fn read(&mut self, dst: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an [Iterator] over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.
