Parse

template<typename T>

auto ydb::Parse

inlineconstexpr

Initial value:

= [](NYdb::TValueParser& parser, const ParseContext& context) -> T {
    
    
    return ValueTraits<T>::Parse(parser, context);
}

A shorthand for calling ydb::ValueTraits<T>::Parse.

Definition at line 53 of file traits.hpp.

Write

auto ydb::Write

inlineconstexpr

Initial value:

= [](auto& builder, auto&& value) {
    
    
    using RawValueType = std::remove_const_t<std::remove_reference_t<decltype(value)>>;
    using ValueType =
        std::conditional_t<std::is_convertible_v<RawValueType, std::string_view>, std::string, RawValueType>;
    ValueTraits<ValueType>::Write(builder, value);
}

A shorthand for calling ydb::ValueTraits<T>::Write.
