Struct QRMatrix 

pub struct QRMatrix {
    pub version: u8,
    pub size: usize,
    pub modules: Vec<Vec<Module>>,
}

The QR module matrix.

Fields

version: u8

size: usize

modules: Vec<Vec<Module>>

Implementations

impl QRMatrix

pub fn new(version: u8) -> Self

Create a new empty matrix for the given version. All modules start as Data(false).

pub fn is_micro(&self) -> bool

Whether this matrix uses Micro QR sizing (11×11 … 17×17).

pub fn set(&mut self, i: usize, j: usize, module: Module)

Set a module at (col, row).

pub fn get(&self, i: usize, j: usize) -> Module

Get the module at (i, j).

pub fn data_at(&self, i: usize, j: usize) -> Option<bool>

Get the boolean value at (i, j) for data modules.

pub fn size(&self) -> usize

Get size (modules per side).

pub fn place_function_patterns(&mut self)

Place all function patterns for this version, plus reserve the format-info (and, for v ≥ 7, version-info) areas so that data placement skips over them.

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.
