template<typename BasicJsonType , typename InputAdapterType , typename SAX = json_sax_dom_parser<BasicJsonType>>

bool nlohmann::detail::binary_reader< BasicJsonType, InputAdapterType, SAX >::get_ubjson_size_type ( std::pair< std::size_t, char_int_type > &  result )

inlineprivate

determine the type and size for a container

In the optimized UBJSON format, a type and a size can be provided to allow for a more compact representation.

Parameters

[out]

result

pair of the size and the type

Returns

whether pair creation completed
