Struct bzip2::reader::BzCompressor

pub struct BzCompressor<R>(_);

A compression stream which wraps an uncompressed stream of data. Compressed data will be read from the stream.

Methods

impl<R: Read> BzCompressor<R>

fn new(r: R, level: Compress) -> BzCompressor<R>

Create a new compression stream which will compress at the given level to read compress output to the give output stream.

fn into_inner(self) -> R

Unwrap the underlying writer, finishing the compression stream.

Trait Implementations

impl<R: Read> Read for BzCompressor<R>

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

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

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, placing them into 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 chars(self) -> Chars<Self>

Unstable (io)

: the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

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.
