Fast_QR

fast_qr generates QRCodes approximately 5-6x faster than qrcode crate. This test was done using time tool and generating 10k QRCodes of version 40.

You can create a QR as

• Raw matrix
• Vectorized image
• Image

Example

use fast_qr::{ECL, Version, QRBuilder};

let qrcode = QRBuilder::new("https://example.com/".into())
    .ecl(ECL::H)
    .version(Version::V03)
    .build();

// It is preferable to check qrcode result before
qrcode.unwrap().print();

Build WASM

wasm-pack build --target web # All ready in ./pkg

Or find a bundled version in the latest release

lib.rs:

Example

use fast_qr::{ECL, Version, QRBuilder};

let qrcode = QRBuilder::new("https://example.com/".into())
    .ecl(ECL::H)
    .version(Version::V03)
    .build();
// It is preferable to check qrcode result before
qrcode.unwrap().print();

Example SVG

use fast_qr::{ECL, Version, QRBuilder};

let qrcode = QRBuilder::new("https://example.com/".into())
    .ecl(ECL::H)
    .version(Version::V03)
    .build();

let svg = fast_qr::convert::svg::SvgBuilder::new()
    .shape(fast_qr::convert::svg::SvgShape::RoundedSquare)
    .build_qr(qrcode.unwrap());

println!("{}", svg);
