pub struct Xoroshiro64StarStar { /* private fields */ }
Expand description

A Xoroshiro64** random number generator.

The xoshiro64** algorithm is not suitable for cryptographic purposes, but is very fast and has excellent statistical properties.

The algorithm used here is translated from the xoroshiro64starstar.c reference source code by David Blackman and Sebastiano Vigna.
