Call the specified functor for each key-value pair whose key starts with the specified prefix. The functor should be a callable object that accepts two parameters: const bsl::string_view& for the key and t_VALUE& for the value. Return the number of times the functor was called. The order of visitation is unspecified. Noteice that the functor is able to modify the value.
