Struct brotli2::bufread::BrotliEncoder

pub struct BrotliEncoder<R: BufRead> { /* fields omitted */ }

A brotli encoder, or compressor.

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

Methods

impl<R: BufRead> BrotliEncoder<R>

fn new(r: R, level: u32) -> BrotliEncoder<R>

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

The level argument here is typically 0-11.

fn set_params(&mut self, params: &CompressParams)

Creates a new encoder with a custom CompressParams.

fn get_ref(&self) -> &R

Acquires a reference to the underlying stream

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

Acquires a mutable reference to the underlying stream

Note that mutation of the stream may result in surprising results if this encoder is continued to be used.

fn into_inner(self) -> R

Consumes this encoder, returning the underlying reader.

Trait Implementations

impl<R: BufRead> Read for BrotliEncoder<R>

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

Unstable (io)

: the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

fn chain<R>(self, next: R) -> Chain<Self, R> where R: Read

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.
