Classes
struct	vir::as_tuple< T >
	Defines the member type type to a std::tuple specialization matching the non-static data members of T. More...

Namespaces
namespace	vir
	This namespace collects libraries and tools authored by Matthias Kretz.

Concepts
concept	vir::reflectable_struct
	Satisfied if T can be used with the following functions and types.

Typedefs
template<std::size_t N, reflectable_struct T>
using	vir::struct_element_t = std::remove_reference_t<decltype(struct_get<N>(std::declval<T &>()))>
	struct_element_t<N, T> is an alias for the type of the N -th non-static data member of T.
template<typename T>
using	vir::as_tuple_t = typename as_tuple<T>::type
	Alias for a std::tuple specialization matching the non-static data members of T.
template<typename T>
using	vir::as_pair_t = typename as_pair<T>::type
	Alias for a std::pair specialization matching the non-static data members of T.

Functions
template<std::size_t N, reflectable_struct T> requires (N < struct_size_v<std::remove_cvref_t<T>>)
constexpr decltype(auto)	vir::struct_get (T &&obj)
	Returns a cv-qualified reference to the N -th non-static data member in obj.
template<reflectable_struct T>
constexpr auto	vir::to_tuple (T &&obj)
	Returns a std::tuple with a copy of all the non-static data members of obj.
template<reflectable_struct T>
constexpr auto	vir::to_tuple_ref (T &&obj)
	Returns a std::tuple of lvalue references to all the non-static data members of obj.
template<typename T> requires (struct_size_v<std::remove_cvref_t<T>> == 2)
constexpr auto	vir::to_pair (T &&obj)
	Returns a std::pair with a copy of all the non-static data members of obj.
template<typename T> requires (struct_size_v<std::remove_cvref_t<T>> == 2)
constexpr auto	vir::to_pair_ref (T &&obj)
	Returns a std::pair of lvalue references to all the non-static data members of obj.

Variables
template<typename T>
constexpr std::size_t	vir::struct_size_v = 0
	The number of non-static data members of T.
