QR code and Micro QR code encoder in Rust. [Documentation](https://docs.rs/qrcode).
Cargo.toml
----------
```toml
[dependencies]
qrcode = "0.4"
```
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 = "0.4", 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:
