Struct PercolationGrid 

pub struct PercolationGrid {
    pub width: usize,
    pub height: usize,
    pub sites: Vec<bool>,
}

A 2D percolation grid where each site is either open (true) or closed (false).

Fields

width: usize

height: usize

sites: Vec<bool>

Flattened row-major grid. sites[y * width + x] = true if site (x,y) is open.

Implementations

impl PercolationGrid

pub fn new(width: usize, height: usize) -> Self

Create an empty (all closed) grid.

pub fn is_open(&self, x: usize, y: usize) -> bool

Check if site (x, y) is open.

pub fn set(&mut self, x: usize, y: usize, open: bool)

Set site (x, y).

pub fn open_count(&self) -> usize

Count of open sites.

pub fn open_fraction(&self) -> f64

Fraction of open sites.
