Functions

template<typename ...T> constexpr Attrs<std::decay_t<T>...> MakeAttrs(T&&... props): An alternative syntax for creating attribute packs. Takes any number of attributes and returns a pack containing each of those attributes.

template<typename I, typename R, typename ...A> constexpr auto Reduce(I &&init, R &&reducer, A&&... attrs)

template<typename F, typename ...A> constexpr void MergeForeach(F &&callback, A&&... attrs)

template<typename F, typename ...A> constexpr void Foreach(F &&callback, A&&... attrs)

using attributes_t = Attrs 

using pack_t = TypePack<T...>

Public Functions

inline constexpr Attrs()

template<class U0, class ...U> inline constexpr Attrs(U0 &&arg, U&&... args)

template<typename F> inline Attrs &operator=(F &&from)

template<class ...U> inline constexpr auto operator()(U&&... args) &: Provide a call operator for attribute packs. This will attempt to call each member of the attribute pack with the given arguments, and maps the result of that call into a new parameter pack as the same attribute. If one of the members of the pack cannot be called with the given pack, then it is put into the new pack unchanged. Mostly, this is meant to allow the opengl plotting library to do mapping operations

template<class ...U> inline constexpr auto operator()(U&&... args) const &

template<class ...U> inline constexpr auto operator()(U&&... args) &&

template<class ...U> inline constexpr auto operator()(U&&... args) const &&

template<class ...U> inline constexpr bool operator==(const Attrs<U...> &other) const: Attribute packs support equals and not equals, but are not orderable, as the members are not considered to be ordered from the user’s perspective.
