Struct async_compression::write::ZstdDecoder

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

This is supported on feature="write" and feature="zstd" only.

A zstd decoder, or uncompressor.

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

Methods

impl<W: AsyncWrite> ZstdDecoder<W>

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

This is supported on feature="write" only.

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

pub fn get_ref(&self) -> &W

This is supported on feature="write" only.

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

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

This is supported on feature="write" only.

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>

This is supported on feature="write" only.

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

This is supported on feature="write" only.

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.
