Struct MeowRng

pub struct MeowRng { /* private fields */ }

A pseudo-random number generator.

This RNG is initialized with a seed, and from that point generates bits deterministically from that seed. Crucially, these bits are determined solely by that seed, and not by how they’re pulled from the RNG. Pulling bytes by chunks of 8, or chunks of 16, or 32, etc. will yield the same bytes.

Treating the RNG as an unstructured stream makes it more easy to produce consistent results. Refactoring the code to use a larger buffer won’t change the results, for example.

Implementations

impl MeowRng

pub fn new(seed: &[u8; 32]) -> Self

Create a new RNG from a seed.
