### Serialize/Deserialize std::deque with PicoJSON

Source: https://github.com/kazuho/picojson/wiki/Home

Provides C++ template functions to serialize a `std::deque` into a `picojson::array` and deserialize a `picojson::array` back into a `std::deque`. This facilitates data exchange using JSON format.

```cpp
template<typename T>
picojson::value toJson(const std::deque<T>& items)
{
    picojson::array arr;

    for(const auto& i: items)
    {
        arr.push_back(picojson::value>(i));
    }

    return picojson::value(arr);
}

template<typename T>
std::deque<T>& fromJson(std::deque<T>& items, const picojson::value& input)
{
    if(input.is<picojson::array>())
    {
        const auto& array = input.get<picojson::array>();
        for(const auto a: array)
        {
            items.push_back(a.get<T>());
        }
    }

    return items;
}
```

### Pretty JSON Serialization

Source: https://github.com/kazuho/picojson/wiki/FAQ

This snippet demonstrates how to serialize a picojson value into an indented, human-readable JSON format. Use the `serialize(true)` method for pretty-printing.

```cpp
std::cout << myValue.serialize(true);
```
