### Kupyna Hashing Example

Source: https://docs.rs/kupyna

Demonstrates how to use the Kupyna256 hasher to compute a hash of a message.

```APIDOC
## Usage Example

### Description
This example shows how to initialize a Kupyna256 hasher, update it with data, and finalize the hash calculation.

### Code
```rust
use hex_literal::hex;
use kupyna::{Digest, Kupyna256};

let mut hasher = Kupyna256::default();
hasher.update(b"my message");
let hash = hasher.finalize();

assert_eq!(hash, hex!("538e2e238142df05e954702aa75d6942cebe30d44bd514df365d13bdcb6b1458"));
```
```
