Struct bzip2_rs::decoder::DecoderReader

pub struct DecoderReader<R> { /* fields omitted */ }

A high-level decoder that wraps a Read and implements Read, yielding decompressed bytes

use std::fs::File;
use std::io;

use bzip2_rs::DecoderReader;

let mut compressed_file = File::open("tests/samplefiles/sample1.bz2")?;
let mut output = File::create("output.ref")?;

let mut reader = DecoderReader::new(compressed_file);
io::copy(&mut reader, &mut output)?;

Implementations

impl<R> DecoderReader<R>

pub fn new(reader: R) -> Self

Construct a new decoder from something implementing Read

Trait Implementations

impl<R: Read> Read for DecoderReader<R>

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

Decompress bzip2 data from the underlying reader

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

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

pub 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.

pub 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.

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

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

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

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

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

Read the exact number of bytes required to fill buf.

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

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

pub fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

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

Creates an adaptor which will chain this stream with another.

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

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