Detailed Description

template<typename To, typename From, typename Derived = void>
struct wpi::UniquePtrCast< To, From, Derived >

This cast trait provides std::unique_ptr casting.

It has the semantics of moving the contents of the input unique_ptr into the output unique_ptr during the cast. It's also a good example of how to implement a move-only cast.
