Manual usage
Put the following dependency into your project's dependences section:

xxhash3

D implementation of the xxhash library 0.81 including xxh32, xxh64, xxh364 and xxh3128 hashes.

Prerequisites

  • A recent D compiler (DMD, LDC2, GDC)
  • DUB

How to use

  • Include this package as a dub dependancy
  • Use
import xxhash3;      /* Import the D module into scope */

Template API:

    ubyte[1024] data;
    XXH_32 xxh;  // OR XXH_64, xxh3_64, xxh3_128
    xxh.start();
    xxh.put(data[]);
    xxh.start(); //Start again
    xxh.put(data[]);
    auto hash = xxh.finish();

OOP API:

    auto xxh = new XXH32Digest();
    ubyte[] hash = xxh.digest("abc");
    assert(toHexString(hash) == "32D153FF", "Got " ~ toHexString(hash));

    //Feeding data
    ubyte[1024] data;
    xxh.put(data[]);
    xxh.reset(); //Start again
    xxh.put(data[]);
    hash = xxh.finish();

Todos

  • Optimize code, cleanups, speed imporovements
  • Expose more XXH API functions
  • Add support for secrets and seeds with XXH3
