parse from Iterator + Sentinel pair?

[leha-bot]

As sometimes we could have input_iterator with some sentinel value (e.g., istream_iterator + N chars which combined into counted_range via std::ranges::views::counted() or another). This also allows us to make a more generic codebase in spirit of modern C++ which also has updated some algorithms and range-based for for using Iterator+Sentinel pair.

Can you provide an example?

This would require changes like this:

    template<typename IteratorType>
    JSON_HEDLEY_WARN_UNUSED_RESULT
    static basic_json parse(IteratorType first,
                            IteratorType last,

template<typename IteratorType>
class iterator_input_adapter

    iterator_input_adapter(IteratorType first, IteratorType last)

  private:
    IteratorType current;
    IteratorType end;

becomes

    template<typename FirstIteratorType, typename LastIteratorType>
    JSON_HEDLEY_WARN_UNUSED_RESULT
    static basic_json parse(FirstIteratorType first,
                            LastIteratorType last,

template<typename FirstIteratorType, typename LastIteratorType>
class iterator_input_adapter

    iterator_input_adapter(FirstIteratorType first, LastIteratorType last)

  private:
    FirstIteratorType current;
    LastIteratorType end;
