Struct CompressWriter 

pub struct CompressWriter<W: Write, C: Compressor> { /* private fields */ }

A writer that compresses data before writing to the inner writer.

Data is buffered and compressed when the buffer is full or when flush() or finish() is called.

Implementations

impl<W: Write, C: Compressor> CompressWriter<W, C>

pub fn new(inner: W, compressor: C) -> Self

Create a new compressing writer with default buffer size.

pub fn with_buffer_size(inner: W, compressor: C, buffer_size: usize) -> Self

Create a new compressing writer with specified buffer size.

pub fn get_ref(&self) -> &W

Get a reference to the inner writer.

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

Get a mutable reference to the inner writer.

pub fn compressor(&self) -> &C

Get a reference to the compressor.

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

Finish compression and flush all remaining data.

This must be called before dropping to ensure all data is written.

Trait Implementations

impl<W: Write, C: Compressor> Drop for CompressWriter<W, C>

fn drop(&mut self)

Executes the destructor for this type.

impl<W: Write, C: Compressor> Write for CompressWriter<W, C>

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.
