Struct QRMatrix 

pub struct QRMatrix { /* private fields */ }

Wrapper around the QR code matrix providing efficient module access.

Implementations

impl QRMatrix

pub fn new(data: &str, options: &QROptions) -> Result<Self>

Create a new QR matrix from data with the specified options.

pub fn size(&self) -> usize

Get the size (width/height) of the QR code in modules.

pub fn module_count(&self) -> usize

Get the module count (same as size for compatibility).

pub fn is_dark(&self, row: usize, col: usize) -> bool

Check if a module at (row, col) is dark.

pub fn is_dark_signed(&self, row: i32, col: i32) -> bool

Check if a module at (row, col) is dark, with signed coordinates. Returns false for out-of-bounds coordinates.

pub fn get_neighbor( &self, row: i32, col: i32, offset_x: i32, offset_y: i32, ) -> bool

Get neighbor state relative to a position.

pub fn is_finder_pattern(&self, row: usize, col: usize) -> bool

Check if a position is part of a finder pattern (corner square). Finder patterns are 7x7 and located at:

• Top-left: (0, 0)
• Top-right: (0, size-7)
• Bottom-left: (size-7, 0)

pub fn is_finder_pattern_outer(&self, row: usize, col: usize) -> bool

Check if a position is part of a finder pattern’s outer square (7x7 border).

pub fn is_finder_pattern_inner(&self, row: usize, col: usize) -> bool

Check if a position is part of a finder pattern’s inner dot (3x3 center).

Trait Implementations

impl Clone for QRMatrix

fn clone(&self) -> QRMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QRMatrix

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

Formats the value using the given formatter.
