Struct Barcode 

pub struct Barcode { /* private fields */ }

A QR Code or a linear barcode, drawn so that every module lands on whole pixels. Scanners need dark on light, so it stays that way in dark themes.

Text the format cannot hold shows why instead of a code nobody can read. Available with the charts feature, on by default.

use ravenrs_widgets::{Barcode, Symbology};

let link = Barcode::qr("https://example.com").alt("Link to the example site");
let product = Barcode::new(Symbology::Ean13, "789123456789").size(240.0, 110.0);
