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();
|
