I wanted to add full compression support to Rust. Full support means
stream compression (good for http compression) and multiple call
compression (compressing large file with multiple batches of read).
To get to that point, the miniz.cpp and deflate API in Rust runtime
need to be enhanced to overcome a few limitations.
I've worked with the author of miniz.c (Rich Geldreich) to merge
changes into miniz.c on his codeline for the needed API for Rust, and
resolved the decompression bug in miniz's code when working with
gzip'ed file.

Awesome!
I've implemented a full set of deflate API in Rust to support stream
compression and multiple call compression, with caller-driven and
callee-driven pipe style API. Also I've written the Rust GZip
library with stream support like GZipReader and GZipWriter. For
testing, I've re-implemented most of the gzip command line program on
top of the Rust GZip library. Some performance data for the
interested: Rust compression is about 1.8 times slower, decompression
is about 3 times slower than gzip. Overall it seems solid. See
https://github.com/williamw520/rustyzip for the source.
Even more awesome!
Now I need help to merge the changes into the Rust master codeline.
There are couple things.
1. What license to assign for the new files? I use MPL currently.
APL2/MIT dual license. Just copy the same headers that exist on all
the other .rs files.
Er, that's ASL2 (Apache License 2.0)
