RandXoshiro256PlusPlus Class

An implementation of the xoshiro256++ PRNG which stores state in 4 x 64-bit numbers. The authors call it: one of our all-purpose, rock-solid generators. It has excellent(sub-ns) speed, a state(256 bits) that is large enough for any parallel application, and it passes all tests we are aware of.
