Remarks

Single-ownership smart pointer in the vein of std::unique_ptr. Use this when you need an object's lifetime to be strictly bound to the lifetime of a single smart pointer.

This class is non-copyable - ownership can only be transferred via a move operation, e.g.:

TUniquePtr Ptr1(new MyClass); // The MyClass object is owned by Ptr1. TUniquePtr Ptr2(Ptr1); // Error - TUniquePtr is not copyable TUniquePtr Ptr3(MoveTemp(Ptr1)); // Ptr3 now owns the MyClass object - Ptr1 is now nullptr.

If you provide a custom deleter, it is up to your deleter to handle null pointers. This is a departure from std::unique_ptr which will not invoke the deleter if the owned pointer is null: https://en.cppreference.com/w/cpp/memory/unique_ptr/~unique_ptr
