About Move Semantics

This part of the series is all about move semantics. I will introduce the feature to you in an maybe unconventional but easy-to-understand way. Move semantics are nothing special, afterall.

We'll start looking at what move semantics is, how it works, and why we should most s stay away from std::move. We establish some rules about when to use std::move, when std::forward. You learn about why not to move return values or temporary objects. You want to get the best speed from your custom data type and the STL No problem, you will learn what your class must look like to achieve this.

In the end, you also learn about some feature that is not seen that often, ref-qualifiers, how they work, why they are there, and when to use them.

All in all, after having read this book, you have a solid understanding of move semantics.
