Struct async_compression::futures::bufread::BrotliEncoder

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

Available on crate features futures-io and brotli only.

A brotli 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.

Implementations

impl<R: AsyncBufRead> BrotliEncoder<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.

pub fn with_quality_and_params( inner: R, level: Level, params: EncoderParams ) -> Self

Creates a new encoder, using the specified compression level and parameters, which will read uncompressed data from the given stream and emit a compressed stream.

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 BrotliEncoder<R>

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 BrotliEncoder<R>

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

Formats the value using the given formatter.
