Methods

  • constexpr IndexedVariant(const std::variant< Types… > & wrapped, const std::array< uint8_t, sizeof…(Types)> & index)
    Constructor. Wraps the given variant, and takes in a reference to the array of indexes.

  • constexpr uint8_t user_index()
    Returns the user-defined index that is active for this variant.

  • size_t variant_index(uint8_t user_index)
    Returns the variant index that is active for this variant, based on the given user index.

  • constexpr std::variant< Types… > & operator*()
    Returns the actual variant that we are wrapping.

  • constexpr const std::variant< Types… > & operator*()
    Returns the actual variant that we are wrapping.

  • IndexedVariant< Types… > & self()
