| template<std::size_t Index, typename... TArgs> |
| constexpr | Oneof (std::in_place_index_t< Index > index, TArgs &&... args) |
| | Creates oneof wrapper initializing index field.
|

| constexpr bool | Contains (std::size_t index) const noexcept |
| | Returns true of oneof contains index field.
|
| |
| constexpr bool | ContainsAny () const noexcept |
| | Returns true of oneof contains some field.
