Struct async_compression::tokio_02::write::ZstdDecoder

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

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

A zstd decoder, or decompressor.

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

Implementations

impl<W: AsyncWrite> ZstdDecoder<W>

pub fn new(read: W) -> ZstdDecoder<W>

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

pub fn get_ref(&self) -> &W

Acquires a reference to the underlying reader that this decoder is wrapping.

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

Acquires a mutable reference to the underlying reader that this decoder is wrapping.

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

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

Acquires a pinned mutable reference to the underlying reader that this decoder is wrapping.

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

pub fn into_inner(self) -> W

Consumes this decoder returning the underlying reader.

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

Trait Implementations

impl<W: AsyncWrite> AsyncWrite for ZstdDecoder<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 ZstdDecoder<W>

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

Formats the value using the given formatter.

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