Classes
struct	wpi::util::detail::TypesAreDistinct< T, Us >
struct	wpi::util::detail::TypesAreDistinct< T >
struct	wpi::util::TypesAreDistinct<>
struct	wpi::util::TypesAreDistinct< Ts >
	Determine if all types in Ts are distinct. More...
struct	wpi::util::FirstIndexOfType< T, U, Us... >
struct	wpi::util::FirstIndexOfType< T, T, Us... >
struct	wpi::util::pointer_union_detail::GetFirstType< T,... >
	Find the first type in a list of types. More...
class	wpi::util::pointer_union_detail::PointerUnionUIntTraits< PTs >
	Provide PointerLikeTypeTraits for void* that is used by PointerUnion for the template arguments. More...
class	wpi::util::pointer_union_detail::PointerUnionMembers< Derived, ValTy, I >
class	wpi::util::pointer_union_detail::PointerUnionMembers< Derived, ValTy, I, Type, Types... >
class	wpi::util::PointerUnion< PTs >
	A discriminated union of two or more pointer types, with the discriminator in the low bit of the pointer. More...
struct	wpi::util::CastInfoPointerUnionImpl< PTs >
	We can't (at least, at this moment with C++14) declare CastInfo as a friend of PointerUnion like this: More...

Namespaces
namespace	wpi
namespace	wpi::util
namespace	wpi::util::detail
	These are wrappers over isa* function that allow them to be used in generic algorithms such as wpi::util:all_of, wpi::util::none_of, etc.
namespace	wpi::util::pointer_union_detail

Typedefs
template<size_t I, typename... Ts>
using	wpi::util::TypeAtIndex = std::tuple_element_t<I, std::tuple<Ts...>>
	Find the type at a given index in a list of types.

Functions
constexpr int	wpi::util::pointer_union_detail::bitsRequired (unsigned n)
	Determine the number of bits required to store integers with values < n.
template<typename... Ts>
constexpr int	wpi::util::pointer_union_detail::lowBitsAvailable ()
