Struct ZstdDecoder 

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

Available on crate feature zstd only.

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

impl<W: AsyncWrite> ZstdDecoder<W>

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

Available on crate feature tokio 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

Available on crate feature tokio only.

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

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

Available on crate feature tokio 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>

Available on crate feature tokio 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

Available on crate feature tokio 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<W: AsyncWrite> AsyncWrite for ZstdDecoder<W>

Available on crate feature tokio only.

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

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempts to flush the object, ensuring that any buffered data reach their destination.

fn poll_shutdown(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

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

Like poll_write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl<W: Debug> Debug for ZstdDecoder<W>

Available on crate feature tokio only.

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

Formats the value using the given formatter.

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

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

Available on crate feature tokio only.
