Struct QrCode 

pub struct QrCode { /* private fields */ }

A generated QR code ready for SVG rendering.

Create with QrCode::new (default error correction) or QrCode::with_ecl (explicit level), then render via QrCode::to_svg.

Example

use modo::qrcode::{QrCode, QrStyle, Ecl};

let qr = QrCode::with_ecl("https://example.com", Ecl::High).unwrap();
let svg = qr.to_svg(&QrStyle::default()).unwrap();
assert!(svg.starts_with("<svg"));

Implementations

impl QrCode

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

Generate a QR code matrix with default error correction (Ecl::Medium).

Returns QrError::DataTooLong if the input exceeds QR capacity.

pub fn with_ecl(data: &str, ecl: Ecl) -> Result<Self, QrError>

Generate a QR code matrix with the specified error correction level.

Returns QrError::DataTooLong if the input exceeds QR capacity for the chosen level.

pub fn to_svg(&self, style: &QrStyle) -> Result<String, QrError>

Render the QR code as an SVG string.

The SVG uses a viewBox (no fixed width/height) so it scales to its container. Returns QrError::InvalidColor if any color in style is malformed.

pub fn size(&self) -> usize

Returns the number of modules along one side of the QR matrix.

This is the raw matrix dimension (e.g. 21 for Version 1) and does not include the quiet zone added during SVG rendering.

Trait Implementations

impl Debug for QrCode

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

Formats the value using the given formatter.
