QR code and Micro QR code encoder in Rust. Documentation.
[dependencies]
qrcode-rs = "0.1"
The default settings will depend on the image
crate. If you don't need image generation capability, disable the default-features
:
[dependencies]
qrcode-rs = { version = "0.1", default-features = false }
use qrcode_rs::QrCode;
use image::Luma;
fn main() {
// Encode some data into bits.
let code = QrCode::new(b"01234567").unwrap();
// Render the bits into an image.
let image = code.render::<Luma<u8>>().build();
// Save the image.
image.save("/tmp/qrcode.png").unwrap();
}
Generates this image:
use qrcode_rs::QrCode;
fn main() {
let code = QrCode::new(b"Hello").unwrap();
let string = code.render::<char>()
.quiet_zone(false)
.module_dimensions(2, 1)
.build();
println!("{}", string);
}

use qrcode_rs::{QrCode, Version, EcLevel};
use qrcode_rs::render::svg;
fn main() {
let code = QrCode::with_version(b"01234567", Version::Micro(2), EcLevel::L).unwrap();
let image = code.render()
.min_dimensions(200, 200)
.dark_color(svg::Color("#800000"))
.light_color(svg::Color("#ffff80"))
.build();
println!("{}", image);
}
Generates this SVG:
use qrcode_rs::QrCode;
use qrcode_rs::render::unicode;
fn main() {
let code = QrCode::new("mow mow").unwrap();
let image = code.render::<unicode::Dense1x2>()
.dark_color(unicode::Dense1x2::Light)
.light_color(unicode::Dense1x2::Dark)
.build();
println!("{}", image);
}
