It is better to move *it != '[' && *it != '{' to a separate function is_opening, the meaning will be clearer.
For the very least surround with parenthesis, don't count on operator && precedence over ||.

I don't like parens that aren't needed generally... I'll try to add is_opening

It is better to leave a blank line between functions.
Fix if you'll have some other changes to this file.

final can serve as a C++ keyword in other context, better to use other name. result?

This is a utility function I used in one PoC that thought would be useful to have in rsutils, especially now that we're making a bigger use of json.
It also adds what I consider a very useful utility
slice, similar to astring_view. For example, I wanted to refer to the json string insideflexible_msgbut it's not null-teminated. The easy way is by using a slice:LOG_DEBUG( "publishing metadata: " << shorten_json_string( slice( md.custom_data< char const >(), md._data.size() )));Anyway I didn't want to lose this so decided to PR.
