Struct SceneRng 

pub struct SceneRng { /* private fields */ }

Deterministic xorshift, so scenes are reproducible across runs and machines.

Implementations

impl SceneRng

pub const fn new(seed: u64) -> Self

Seed the generator. Zero is remapped: xorshift is stuck at zero.

pub fn next_u64(&mut self) -> u64

Next raw value.

pub fn coordinate(&mut self, bound: i64) -> f64

Integer coordinate in [-bound, bound).

Integers, not arbitrary floats: they keep the degenerate constructions below exactly degenerate, which is the entire point of the scene.

Trait Implementations

impl Clone for SceneRng

fn clone(&self) -> SceneRng

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SceneRng

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
