Method dump

native/thirdpart/json/json.hpp:13837–14030

! @brief internal implementation of the serialization function This function is called by the public member function dump and organizes the serialization internally. The indentation level is propagated as additional parameter. In case of arrays and objects, the function is called recursively. - strings and object keys are escaped using `escape_string()` - integer numb

    @param[in] current_indent  the current indent level (only used internally)
