Struct ZstdDecoder 

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

Available on crate feature zstd only.

A zstd 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> ZstdDecoder<R>

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

Available on crate feature futures-io only.

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)

Available on crate feature futures-io only.

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

Available on crate feature futures-io only.

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

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

Available on crate feature futures-io 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 R>

Available on crate feature futures-io 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) -> R

Available on crate feature futures-io 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.

Trait Implementations

impl<R: AsyncBufRead> AsyncRead for ZstdDecoder<R>

Available on crate feature futures-io only.

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

Attempt to read from the AsyncRead into buf.

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

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl<R: Debug> Debug for ZstdDecoder<R>

Available on crate feature futures-io only.

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

Formats the value using the given formatter.

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

where PinnedFieldsOf<__Origin<'__pin, R>>: Unpin,

Available on crate feature futures-io only.
