Struct async_compression::futures::bufread::XzDecoder

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

Available on crate features futures-io and xz only.

A xz 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> XzDecoder<R>

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

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

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.
