Struct SplitMix64

pub struct SplitMix64(pub u64);

A splitmix64 random number generator.

The splitmix algorithm is not suitable for cryptographic purposes, but is very fast and has a 64 bit state.

The algorithm used here is translated from the splitmix64.c reference source code by Sebastiano Vigna. For next_u32, a more efficient mixing function taken from dsiutils is used.
