Struct ZlibEncoder 

pub struct ZlibEncoder<R: Write> { /* private fields */ }

Zlib compression Basically a wrapper to Encoder which sets the codec for you.

Implementations

impl<W: Write> ZlibEncoder<W>

pub fn new(writer: W, level: CompressionLevel) -> Self

pub fn get_ref_mut(&mut self) -> &mut W

Mutable reference to underlying reader, not advisable to modify during reading.

pub fn get_ref(&self) -> &W

pub fn finish(self) -> Result<W>

Call flush and return the inner writer

pub fn total_out(&self) -> usize

total bytes written to the writer, inclusive of all streams if flush has been called before

pub fn total_in(&self) -> usize

total bytes processed, inclusive of all streams if flush has been called before

Trait Implementations

impl<W: Write> Write for ZlibEncoder<W>

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

Writes a buffer into this writer, returning how many bytes were written.

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

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

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

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

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

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

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

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

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

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

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
