qrcode-rust

QR code and Micro QR code encoder in Rust. Documentation.

Cargo.toml

toml [dependencies] qrcode = "0.2.0"

The default settings will depend on the image crate. If you don't need image generation capability, disable the default-features:

toml [dependencies] qrcode = { version = "0.2.0", default-features = false }

Example

This code:

```rust extern crate qrcode; extern crate image;

use qrcode::QrCode; use image::GrayImage;

fn main() { // Encode some data into bits. let code = QrCode::new(b"01234567").unwrap();

// Render the bits into an image.
let image: GrayImage = code.render().to_image();

// Save the image.
image.save("/tmp/qrcode.png").unwrap();

} ```
