Classes
struct	a_util::underlying_type_or_type< T, bool >
	Retrieves the underlying type if T is an enum, otherwise the type itself. More...
struct	a_util::underlying_type_or_type< T, true >
	Retrieves the underlying type of the enum type T. More...
struct	a_util::is_explicitly_convertible_to< T, U >
	Checks if there is an explicitly defined conversion from U to T. More...

Namespaces
namespace	a_util
	Serves as the root component, with common functionality documented in core functionality.

Typedefs
template<class T, bool is_enum = std::is_enum_v<T>>
using	a_util::underlying_type_or_type_t = typename underlying_type_or_type<T, is_enum>::type
	Retrieves the underlying type if T is an enum, otherwise the type itself.

Variables
template<typename T>
constexpr bool	std::is_enum_v = is_enum<T>::value
template<class T, class U>
constexpr bool	a_util::is_explicitly_convertible_to_v = is_explicitly_convertible_to<T, U>::value
