Struct BzEncoder
pub struct BzEncoder<R> { /* private fields */ }A bz2 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.
Implementations
impl<R> BzEncoder<R>
fn get_ref(&self) -> &RAcquires a reference to the underlying stream
fn get_mut(&mut self) -> &mut RAcquires 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) -> RConsumes this encoder, returning the underlying reader.
fn total_out(&self) -> u64Returns the number of bytes produced by the compressor (e.g. the number of bytes read from this stream)
Note that, due to buffering, this only bears any relation to total_in() when the compressor chooses to flush its data (unfortunately, this won't happen in general at the end of the stream, because the compressor doesn't know if there's more data to come). At that point,
total_out() / total_in()would be the compression ratio.fn total_in(&self) -> u64Returns the number of bytes consumed by the compressor (e.g. the number of bytes read from the underlying stream)
impl<R: BufRead> BzEncoder<R>
fn new(r: R, level: Compression) -> SelfCreates a new encoder which will read uncompressed data from the given stream and emit the compressed stream.
