Struct lz4::Encoder

pub struct Encoder<W> { /* fields omitted */ }

Methods

impl<W: Write> Encoder<W>

pub fn writer(&self) -> &W

Immutable writer reference.

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

This function is used to flag that this session of compression is done with. The stream is finished up (final bytes are written), and then the wrapped writer is returned.

Trait Implementations

impl<W: Write> Write for Encoder<W>

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

Write a buffer into this writer, 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_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize, Error>

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

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, 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.
