Struct SimpleRng 

pub struct SimpleRng { /* private fields */ }

Self-contained, seed-based 64-bit pseudo-random number generator (SplitMix64).

Designed to provide deterministic, platform-independent random number generation without pulling in external dependencies like rand.

Implementations

impl SimpleRng

pub fn new(seed: u64) -> Self

Creates a new PRNG with the specified 64-bit seed.

pub fn next_u64(&mut self) -> u64

Generates the next pseudo-random 64-bit unsigned integer.

pub fn next_f64(&mut self) -> f64

Generates a pseudo-random f64 in the half-open interval [0.0, 1.0).

pub fn next_range(&mut self, min: f64, max: f64) -> f64

Generates a pseudo-random f64 uniformly distributed in [min, max).

pub fn next_gaussian(&mut self) -> f64

Generates a standard normally distributed variable (mean 0.0, std dev 1.0) using the Box-Muller transform.
