Data Structures
struct	ext::has_clone< T >
	Type trait to determine existence of clone method. A boolean field namd value is set to true if provided class (possibly cv-qualified and via reference) has clone method. More...
struct	ext::supports< F(Ts ...) >
struct	ext::index_in< T >
	Specialisation for empty pack, in which case the field is set to false. More...
struct	ext::index_in< T, U, Ts ... >
	Specialisation for non-empty pack where the first type in the pack is different from the tested type, in which case the field is set to result of the recursive test on shorter pack. More...
struct	ext::index_in< T, T, Ts ... >
	Trait to test whether type T is in a types pack. The trait provides field value set to true if the type T is in pack of types Ts ..., false othervise. More...
struct	ext::casional< >
struct	ext::casional< T >
struct	ext::casional< std::true_type, R, Ts ... >
struct	ext::casional< std::false_type, R, Ts ... >
struct	ext::strip_reference_wrapper< T >
struct	ext::strip_reference_wrapper< std::reference_wrapper< T > >

Typedefs
template<typename T , typename ... Ts>
using	ext::is_in = std::integral_constant< bool,(std::is_same< T, Ts >::value||...) >
	Trait to test whether type T is in a types pack. The trait provides field value set to true if the type T is in pack of types Ts ..., false othervise. More...
template<bool value>
using	ext::boolean = typename std::conditional< value, std::true_type, std::false_type >::type

Functions
template<class F , class ... Ts, typename = decltype ( std::declval < F > ( ) ( std::declval < Ts > ( ) ... ) )>
std::true_type	ext::supports_test (const F &, const Ts &...)
	Positive supports test implementation. The test is designed to detect call availability on callable F with parameters Ts ... More...
std::false_type	ext::supports_test (...)
	Negative supports test implementation. The test is designed to be callback when the positive test failed. More...
