Cvb::Shims Namespace Reference

Namespace to for standard types that are not available in C++14. More...

Classes
class	bad_optional_access
	Error when accessing not set value. More...
class	bad_variant_access
	Error when accessing not set alternative. More...
struct	in_place_t
	Disambiguation tags that can be passed to the constructors of optional() to indicate that the contained object should be constructed in-place. More...
struct	monostate
	Unit type intended for use as a well-behaved empty alternative in variant. More...
struct	nullopt_t
	Indicates optional() type with uninitialized state. More...
class	optional
	This class is a replacement for C++17 std::optional. More...
class	variant
	This class is a replacement for C++17 std::variant. More...
struct	variant_alternative
	Compile-time index access to the type of the alternatives at index I. More...
struct	variant_size
	Get the number of alternatives in a variant. More...

Typedefs
template<size_t I, class T >
using	variant_alternative_t = typename variant_alternative< I, T >::type
	Helper type alias for Shims::variant_alternative.

Functions

template<class T , class... TS>
T &	get (variant< TS... > &var)
template<class T , class... TS>
T	get (variant< TS... > &&var)
template<size_t I, class... TS>
std::add_pointer< variant_alternative_t< I, variant< TS... > > >::type	get_if (variant< TS... > *pvar) noexcept
template<class T , class... TS>
std::add_pointer< T >::type	get_if (variant< TS... > *pvar) noexcept
	class...>(const variant<TS...> &) More...

Variables
static constexpr nullopt_t	nullopt = {}
	Tag to indicate an #optional not containing a value.
static constexpr in_place_t	in_place {}
	Tag to indicate an Optional to in-place construct a value.
static const constexpr size_t	variant_npos = size_t(-1)
	Returned by variant::index() on invalid state.
