How to serialize JSON to std::vector<uint8_t>?

[db4]

I would like to do the same as json::dump() but placing the result into a vector of bytes. What's the recommended way to do that?

This is currently not possible out of the box. You would need to serialize to a std::string and then create a vector out of that:

auto str = j.dump();
std::vector<std::uint8_t> data(str.begin(), str.end());

So it cannot be done without copying the string to a vector. OK, got it.
