Struct autocompress::Encoder

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

structure of encoding writer

Methods

impl<W: Write> Encoder<W>

pub fn new(
    writer: W,
    format: Format,
    compression_level: CompressionLevel
) -> Result<Self>

create new encoder with a writer, a format and a compression level.

let mut encoder = Encoder::new(
    std::fs::File::create("new-file.txt.gz")?,
    Format::Gzip,
    CompressionLevel::Default
)?;
encoder.write_all(b"hello, world")?;

Trait Implementations

impl<W: Write> Write for Encoder<W>

fn write(&mut self, buf: &[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_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.
