-/// A xoshiro256+ random number generator.
-///
-/// The xoshiro256+ algorithm is not suitable for cryptographic purposes, but
-/// is very fast and has good statistical properties, besides a low linear
-/// complexity in the lowest bits.
-///
-/// The algorithm used here is translated from [the `xoshiro256plus.c`
-/// reference source code](http://xoshiro.di.unimi.it/xoshiro256plus.c) by
-/// David Blackman and Sebastiano Vigna.
