Struct DotMatrix 

pub struct DotMatrix { /* private fields */ }

A sparse 2D dot grid: rows × columns cells where true means a dot is present at that position. Only odd-parity positions ((x + y) % 2 == 1) ever carry true cells from a DotCode encoder; the renderer treats all true cells uniformly.

Implementations

impl DotMatrix

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

Allocate a width × height grid with every cell false.

pub fn width(&self) -> usize

Width in cells.

pub fn height(&self) -> usize

Height in cells.

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

Read a cell. true means a dot is present at (x, y).

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

Write a cell.

Trait Implementations

impl Clone for DotMatrix

fn clone(&self) -> DotMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DotMatrix

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

Formats the value using the given formatter.
