Struct Grid 

pub struct Grid { /* private fields */ }

Implementations

impl Grid

pub fn new(rows: usize, cols: usize) -> Self

pub fn dimensions(&self) -> (usize, usize)

Grid dimensions as (rows, cols).

pub fn rows(&self) -> usize

Number of rows.

pub fn cols(&self) -> usize

pub fn get_mut(&mut self, row: usize, col: usize) -> Option<&mut Cell>

Get a mutable cell reference.

pub fn set(&mut self, row: usize, col: usize, value: TernaryValue)

Set a cell value directly.

pub fn row(&self, row: usize) -> Option<&[Cell]>

Get a whole row.

pub fn col(&self, col: usize) -> Option<Vec<Cell>>

Get a whole column.

pub fn cells(&self) -> Vec<&Cell>

Get all cells flattened.

pub fn range(&self, r1: usize, c1: usize, r2: usize, c2: usize) -> Vec<&Cell>

Get all cells in a range (inclusive).

pub fn range_mut( &mut self, r1: usize, c1: usize, r2: usize, c2: usize, ) -> Vec<&mut Cell>

pub fn is_empty(&self) -> bool

Is the grid empty?

pub fn compute_all_fitness(&mut self)

Compute default fitness for all cells.

pub fn rows_mut(&mut self) -> &mut Vec<Vec<Cell>>
