Struct async_compression::tokio::bufread::GzipEncoder

pub struct GzipEncoder<R> {
    inner: Encoder<R, GzipEncoder>,
}

A gzip encoder, or compressor.

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

Fields

inner: Encoder<R, GzipEncoder>

Implementations

impl<R: AsyncBufRead> GzipEncoder<R>

pub fn new(inner: R) -> Self

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

pub fn with_quality(inner: R, level: Level) -> Self

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

impl<R> GzipEncoder<R>

pub fn get_ref(&self) -> &R

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

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

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

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

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

Acquires a pinned mutable reference to the underlying reader that this encoder is wrapping.

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

pub fn into_inner(self) -> R

Consumes this encoder returning the underlying reader.

Note that this may discard internal state of this encoder, so care should be taken to avoid losing resources when this is called.

Trait Implementations

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

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

Attempts to read from the AsyncRead into buf.

impl<R: AsyncWrite> AsyncWrite for GzipEncoder<R>

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>>

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<R: Debug> Debug for GzipEncoder<R>

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

Formats the value using the given formatter.

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