Struct SplitMix64 

pub struct SplitMix64 { /* private fields */ }

SplitMix64 PRNG for seeding other generators

This is an ultra-fast PRNG specifically designed for seeding other PRNGs. It’s not suitable for cryptographic use but provides excellent quality for initialization purposes.

Implementations

impl SplitMix64

pub fn new(seed: u64) -> Self

Create a new SplitMix64 from a seed

pub fn next_u64(&mut self) -> u64

Generate the next u64 value

pub fn next_u32(&mut self) -> u32

Generate the next u32 value

pub fn fill_bytes(&mut self, dest: &mut [u8])

Fill a buffer with random bytes

pub fn seed_xoshiro256(&mut self) -> [u64; 4]

Generate a seed array for Xoshiro256+

pub fn seed_pcg64(&mut self) -> [u64; 2]

Generate a seed array for PCG64
