epcgen

A rust library with minimal dependencies to help with the type-safe creation of EPC QR codes.
As epcgen only provides the payload for the QR code, it can be used with any QR rendering software.
Take a look at the examples.

Here's a code carrying data generated with epcgen.

lib.rs:

Type-safe creation of EPC QR codes.

Examples

use epcgen::{CharacterSet, Epc, Identification, Version};
use image::Luma;
use qrcode::QrCode;

let iban = "DE90 8306 5408 0004 1042 42";
assert!(epcgen::iban::is_valid(iban));
let unused_ref = "RF45G72UUR";
assert!(epcgen::rf::is_valid(unused_ref));
let builder = Epc::builder()
    .version(Version::V1)
    .character_set(CharacterSet::UTF8)
    .identification(Identification::Sct)
    .bic("GENODEF1SLR")
    .beneficiary("Codeberg e.V.")
    .iban(iban)
    .amount("10.00")
    .remittance(epcgen::Remittance::Text("for the good cause".to_string()));
let epc = builder.build();
let epc = epc.expect("example should work");
let qrcode_payload = epc.to_string();
let code = QrCode::new(qrcode_payload).unwrap();
// Render the data into an image.
let image = code.render::<Luma<u8>>().build();
// Save the image.
image.save("./examples_basic_usage_qrcode.png").unwrap();
