QR code and Micro QR code encoder in Rust. [Documentation](https://kennytm.github.io/qrcode-rust).

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();
}
```

Generates this image:
