Struct DeflateDecoder

pub struct DeflateDecoder<R> { /* private fields */ }

Available on crate features tokio and deflate only.

A deflate decoder, or decompressor

This structure implements an AsyncRead interface and will read compressed data from an underlying stream and emit a stream of uncompressed data.

Implementations

impl<R: AsyncBufRead> DeflateDecoder<R>

pub fn new(read: R) -> DeflateDecoder<R>

Creates a new decoder which will read compressed data from the given stream and emit a uncompressed stream.

impl<R> DeflateDecoder<R>

pub fn multiple_members(&mut self, enabled: bool)

Configure multi-member/frame decoding, if enabled this will reset the decoder state when reaching the end of a compressed member/frame and expect either EOF or another compressed member/frame to follow it in the stream.

pub fn get_ref(&self) -> &R

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

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

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 R>

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) -> R

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<R: AsyncBufRead> AsyncRead for DeflateDecoder<R>

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

Attempts to read from the AsyncRead into buf.

impl<R: AsyncWrite> AsyncWrite for DeflateDecoder<R>

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.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize>>

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

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl<R: Debug> Debug for DeflateDecoder<R>

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

Formats the value using the given formatter.

impl<'__pin, R> Unpin for DeflateDecoder<R>
