Struct async_compression::tokio::write::ZstdDecoder

source · [−]

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

Available on crate features tokio and zstd only.

Expand description

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

source

impl<W: AsyncWrite> ZstdDecoder<W>

source

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.

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.
