Struct flate2::bufread::GzDecoder

pub struct GzDecoder<R: BufRead> {
    // some fields omitted
}

A gzip streaming decoder

This structure exposes a Read interface that will consume compressed data from the underlying reader and emit uncompressed data.

Methods

impl<R: BufRead> DecoderReaderBuf<R>

fn new(r: R) -> Result<DecoderReaderBuf<R>>

Creates a new decoder from the given reader, immediately parsing the gzip header.

If an error is encountered when parsing the gzip header, an error is returned.

fn header(&self) -> &Header

Returns the header associated with this stream.

Trait Implementations

impl<R: BufRead> Read for DecoderReaderBuf<R>

fn read(&mut self, into: &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.
