Binary Size

Preliminary measurements of wuffs genlib libraries' binary size on x86_64 are below. Lower is better.

TODO: re-do these numbers as we've spun std/zlib out of std/deflate.

Comparison

Below are some standard C libraries shipped as part of Debian Testing as of November 2017. The numbers aren't directly comparable, as these libraries have a richer API, especially in providing an encoder and not just a decoder. Still, it is a reference point for e.g. Wuffs (deflate + gzip + zlib) vs libz and Wuffs gif vs libgif.
