Struct async_compression::tokio_02::write::XzEncoder

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

This is supported on crate features tokio-02 and xz only.

A xz encoder, or compressor.

This structure implements an AsyncWrite interface and will take in uncompressed data and write it compressed to an underlying stream.

Implementations

impl<W: AsyncWrite> XzEncoder<W>

pub fn new(inner: W) -> Self

Creates a new encoder which will take in uncompressed data and write it compressed to the given stream.

pub fn with_quality(inner: W, level: Level) -> Self

Creates a new encoder which will take in uncompressed data and write it compressed to the given stream.

pub fn get_ref(&self) -> &W

Acquires a reference to the underlying writer that this encoder is wrapping.

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

Acquires a mutable reference to the underlying writer that this encoder is wrapping.

Note that care must be taken to avoid tampering with the state of the writer which may otherwise confuse this encoder.

pub fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut W>

Acquires a pinned mutable reference to the underlying writer that this encoder is wrapping.

Note that care must be taken to avoid tampering with the state of the writer which may otherwise confuse this encoder.

pub fn into_inner(self) -> W

Consumes this encoder returning the underlying writer.

Note that this may discard internal state of this encoder, so care should be taken to avoid losing resources when this is called.

Trait Implementations

impl<W: AsyncWrite> AsyncWrite for XzEncoder<W>

fn poll_write(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &[u8]
) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempts to flush the object, ensuring that any buffered data reach their destination.

fn poll_shutdown(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

pub fn poll_write_buf<B>(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &mut B
) -> Poll<Result<usize, Error>> where
    B: Buf, 

Writes a Buf into this value, returning how many bytes were written.

impl<W: Debug> Debug for XzEncoder<W>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'__pin, W> Unpin for XzEncoder<W> where
    __Origin<'__pin, W>: Unpin,
