Struct Code 

pub struct Code { /* private fields */ }

An encoded or decoded QR code.

Holds the full module matrix plus metadata (version, EC level, mask number). Convert to a renderable image with Code::render.

payload is populated by Reader; for codes returned from Encoder the input bytes are not retained — refer to the original value instead.

Implementations

impl Code

pub fn version(&self) -> Version

QR version (1–40).

pub fn ec_level(&self) -> EcLevel

Error-correction level used.

pub fn mask(&self) -> u8

Mask pattern (0–7) selected by the encoder or recovered from format info.

pub fn size(&self) -> usize

Side length of the module matrix in modules. Equals 17 + 4 * version.0.

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

Read a single module. true = dark.

pub fn payload(&self) -> &[u8]

Recovered payload bytes (only meaningful for decoded codes).

For codes returned by Encoder::build this is empty — the encoder does not retain the input.

pub fn render(&self) -> RenderBuilder<'_>

Start building a Bitmap from this code.

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a duplicate of the value.

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

Performs copy-assignment from source.
