Struct async_compression::stream::ZstdDecoder

pub struct ZstdDecoder<S: Stream<Item = Result<Bytes>>> { /* fields omitted */ }

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

A zstd decoder, or decompressor.

This structure implements a Stream interface and will read compressed data from an underlying stream and emit a stream of uncompressed data.

Methods

impl<S: Stream<Item = Result<Bytes>>> ZstdDecoder<S>

pub fn new(stream: S) -> Self

This is supported on feature="stream" only.

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

pub fn get_ref(&self) -> &S

This is supported on feature="stream" only.

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

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

This is supported on feature="stream" only.

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

Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this decoder.

pub fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut S>

This is supported on feature="stream" only.

Acquires a pinned mutable reference to the underlying stream that this decoder is wrapping.

Note that care must be taken to avoid tampering with the state of the stream which may otherwise confuse this decoder.

pub fn into_inner(self) -> S

This is supported on feature="stream" only.

Consumes this decoder returning the underlying stream.

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<'__pin, S: Stream<Item = Result<Bytes>>> Unpin for ZstdDecoder<S> where
    __Origin<'__pin, S>: Unpin, 

impl<S: Debug + Stream<Item = Result<Bytes>>> Debug for ZstdDecoder<S>

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

Formats the value using the given formatter.

impl<S: Stream<Item = Result<Bytes>>> Stream for ZstdDecoder<S>

type Item = Result<Bytes>

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut Self>,
    cx: &mut Context
) -> Poll<Option<Result<Bytes>>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
