Can the value_from function add iterator parameters, such as value_from (Iterator begin, Iterator end)

PLEASE DON'T FORGET TO "STAR" THIS REPOSITORY :)

When reporting a bug please include the following:

Version of Boost

You can find the version number in the file <boost/version.hpp>

Steps necessary to reproduce the problem

A small compiling program is the best. If your code is public, you can provide a link to the repository.

All relevant compiler information

If you are unable to compile please include the type and version of compiler you are using as well as all compiler output including the error message, file, and line numbers involved.

The more information you provide the sooner your issue can get resolved!

You didn't explain the desired semantics, so I assume it's supposed to produces a json::value that stores an array. So, my questions are these. Why converting a sequence object doesn't work for you? Where do you get the iterators?

You don't have the required semantics to explain, so I think it should produce a store. Why doesn't converting sequence objects work for you? Where do you get iterators?json::value``array

Due to the large amount of data in my sequential container, I can only send a part of it at a time. Therefore, I need to serialize just this portion, so I expect to transmit the iterator range.

But can't you wrap two iterators into a range-like class? This one should work: https://www.boost.org/doc/libs/1_85_0/libs/range/doc/html/range/reference/utilities/iterator_range.html But if you have access to C++20, this should also work: https://en.cppreference.com/w/cpp/ranges/subrange

good idea，thank you

So, did it work for you? Can I close this?
