Haven't checked it in smhasher yet. just saw this, claiming to be the very best. Well, maybe a PR will come soon. The rust framework for hashes is prepared, there just haven't been any good rust hashes yet.

i know nothing about this algorithm, but I went and checked that already; it does have a PR for smhasher: https://github.com/rurban/smhasher/pull/279

The note in there that the output of the algorithm is different for different SIMD widths seems to indicate that this isn't so much an algorithm as a family of related algorithms

That's a bit weird since it says on the front page that:

> All generated hashes for a given version of GxHash are stable, meaning that for a given input the output hash will be the same across all supported platforms.

The github repo is more recent so maybe it wasn't stable at the time they tried to get it into smhasher from last year?

Looks like the original failed smhasher, since the PR modified the compress function

The article quotes results from smhasher runs.

It passes.
