Struct async_compression::tokio::bufread::BzEncoder

source · 
pub struct BzEncoder<R> { /* private fields */ }
Available on crate features tokio and bzip2 only.
Expand description

A bzip2 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§

source§

impl<R: AsyncBufRead> BzEncoder<R>

source

pub fn new(inner: R) -> Self

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

source

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.

source

pub fn get_ref(&self) -> &R

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

source

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.

source

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.

source

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.
