zopfli-rs
Bindings to zopfli
for deflate, gzip, and zlib compression.
Purpose
zopfli
is already implemented in pure Rust by @carols10cents
(carols10cents/zopfli
), so it might seem duplicative
to create bindings to the original C / C++ library by Google
(google/zopfli
). In order to give better insights into the
performance of the pure Rust library and to give a slightly faster alternative,
zopfli-rs
was made.
Benchmarks
zopfli-rs
just slightly inches ahead of zopfli
when it comes to gzip
compression. Both zopfli-rs
and zopfli
follow a strange performance curve
that seem to be faster for certain sizes of data (in this case ~10KB is the
sweet spot). Changing up the Options
would more than likely improve these
results, but that would take a bit of time to tweak to perfection.
