### Initialize procspawn

Source: https://github.com/mitsuhiko/procspawn/blob/master/README.md

Invoke procspawn::init() early in your program's main function. This ensures that any setup before this point is also available in spawned functions.

```rust
procspawn::init();
```

### Spawn a process with data and retrieve result

Source: https://github.com/mitsuhiko/procspawn/blob/master/README.md

Spawn a new process that takes a serializable argument, performs an operation, and returns a serializable result. The join handle allows retrieving the result after the process completes.

```rust
let data = vec![1, 2, 3, 4];
let handle = procspawn::spawn(data, |data| {
    println!("Received data {:?}", &data);
    data.into_iter().sum::<i64>()
});
let result = handle.join().unwrap();
```
