pub struct ZlibEncoder<W: Write> { /* fields omitted */ }A Zlib encoder/compressor.
A struct implementing a Write interface that takes unencoded data and compresses it to
the provided writer using DEFLATE compression with Zlib headers and trailers.
use std::io::Write;
use deflate::Compression;
use deflate::write::ZlibEncoder;
let data = b"This is some test data";
let mut encoder = ZlibEncoder::new(Vec::new(), Compression::Default);
encoder.write_all(data)?;
let compressed_data = encoder.finish()?;
Create a new ZlibEncoder using the provided compression options.
Encode all pending data to the contained writer, consume this ZlibEncoder,
and return the contained writer if writing succeeds.
Resets the encoder (except the compression options), replacing the current writer
with a new one, returning the old one.
Return the adler32 checksum of the currently consumed data.
Write a buffer into this object, returning how many bytes were written. Read more
Flush the encoder.
This will flush the encoder, emulating the Sync flush method from Zlib.
This essentially finishes the current block, and sends an additional empty stored block to
the writer.
Attempts to write an entire buffer into this write. Read more
Writes a formatted string into this writer, returning any error encountered. Read more
Creates a "by reference" adaptor for this instance of Write. Read more
When the encoder is dropped, output the rest of the data.
WARNING: This may silently fail if writing fails, so using this to finish encoding
for writers where writing might fail is not recommended, for that call
finish() instead.
