hashbench ~refactor-tune-xxhcode

This is a benchmark program for the phobos digests

It can be compiled with all D compilers (at the moment of writting).

It output the benchmark results.

or

Use configurations to build the different variants of the code:
* local-dev - a local copy of the xxh.d source (development aide)
* dub-package - use the xxhash3 DUB package
* phobos-dev - Use std.digest.xxh . You must use the beta DMD compiler in this case
