Struct XzDecoder

source
pub struct XzDecoder<W> { /* private fields */ }
Available on crate features futures-io and xz only.
Expand description

A xz decoder, or decompressor

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

Implementations§

source§

impl<W> XzDecoder<W>

source

pub fn get_ref(&self) -> &W

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

source

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.

source

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.

source

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.

source§

impl<W: AsyncWrite> XzDecoder<W>

source

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

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

source

pub fn with_mem_limit(read: W, memlimit: u64) -> Self

Creates a new decoder with the specified limit of memory.

§Errors

An IO error may be returned during decoding if the specified limit is too small.

Trait Implementations§

source§

impl<W: AsyncBufRead> AsyncBufRead for XzDecoder<W>

source§

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

source§

fn consume(self: Pin<&mut Self>, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to poll_read. Read more
