Vittorio Romeo expands the Dive into C++14 series with a new video covering the implementation of a generic "unique resource" wrapper.

Dive into C++14 - [3]

About the tutorial:

This new tutorial covers the implementation of a generic "unique resource" class, with the same ownership semantics as std::unique_ptr.

std::unique_ptr is not limited to pointer-like handles - by adapting other kinds of handles to the `NullablePointer` concept, it can still be used. Nevertheless, for educational purposes and to understand the commonalities between resource types and handle types, we're going to implement our own std::unique_ptr-like generic "unique wrapper".

The video shows the implementation of the resource class and the abstraction of the behavior of several example resource types (heap-allocated pointers, OpenGL VBOs, int-based-handle APIs).

All the code is available on GitHub. The code segments are thoroughly commented and can be read as a tutorial without watching the video, if preferred.
