Implementations

impl Life

pub fn random(rows: usize, cols: usize, seed: u64, fill: f32) -> Self

pub fn alive(&self, r: usize, c: usize) -> bool

pub fn step(&mut self)

Apply one step of B3/S23. Writes scratch, swaps.

pub fn alive_count(&self) -> usize

pub fn density(&self) -> f32

pub fn row_alive_count(&self, r: usize) -> usize

Cells alive in a single row — used as “fitness” per track.

pub fn col_alive_count(&self, c: usize) -> usize

Cells alive in a single column — used as “present-moment energy”.

pub fn set(&mut self, r: usize, c: usize, alive: bool)

Set a single cell (bounds-safe, wraps).

pub fn inject_glider(&mut self, r0: usize, c0: usize)

Seed a glider near the top-left corner. Useful for non-empty grids that would otherwise die quickly.

pub fn sprinkle(&mut self, seed: &mut u64, count: usize)

Random splash of live cells to jolt a stagnant grid.
