Struct flate2::bufread::GzEncoder

pub struct GzEncoder<R: BufRead> { /* fields omitted */ }

A gzip streaming encoder

This structure exposes a Read interface that will read uncompressed data from the underlying reader and expose the compressed version as a Read interface.

Methods

impl<R: BufRead> EncoderReaderBuf<R>

fn new(r: R, level: Compression) -> EncoderReaderBuf<R>

Creates a new encoder which will use the given compression level.

The encoder is not configured specially for the emitted header. For header configuration, see the Builder type.

The data read from the stream r will be compressed and available through the returned reader.

fn get_ref(&self) -> &R

Acquires a reference to the underlying reader.

fn get_mut(&mut self) -> &mut R

Acquires a mutable reference to the underlying reader.

Note that mutation of the reader may result in surprising results if this encoder is continued to be used.

fn into_inner(self) -> R

Returns the underlying stream, consuming this encoder

Trait Implementations

impl<R: BufRead> Read for EncoderReaderBuf<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.

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, 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>

🔬 This is a nightly-only experimental API. (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 [char]s.

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.

impl<R: BufRead + Write> Write for EncoderReaderBuf<R>

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

Write a buffer into this object, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Attempts to write an entire buffer into this write.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

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

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