matrix-rust-sdk

**matrix-sdk-qrcode** is a crate to easily generate and parse QR codes for

interactive verification using [QR codes] in Matrix.

## Usage

This is probably not the crate you are looking for, it's used internally in the

[matrix-sdk].

If you still want to play with QR codes, here is a helpful example.

### Encode into a QR code

```rust,no_run

use matrix_sdk_qrcode::{QrVerificationData, DecodingError};

use image::Luma;

fn main() -> Result<(), DecodingError> {

    let data = b"MATRIX\

        \x02\x02\x00\x07\

        FLOW_ID\

        AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA\

        BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB\

        SHARED_SECRET";

    let data = QrVerificationData::from_bytes(data)?;

    let encoded = data.to_qr_code().unwrap();

    let image = encoded.render::<Luma<u8>>().build();

    Ok(())

}

```
