Struct Xorshift64 

pub struct Xorshift64 { /* private fields */ }

A fast, seedable Xorshift64 RNG

Not cryptographically secure - suitable for simulation only. Produces a full cycle of 2^64-1 values before repeating

Implementations

impl Xorshift64

pub fn new(seed: u64) -> Self

Creates a new RNG with the given seed.

Seed must be non-zero - passing 0 will be replaced with a default non-zero seed.
