Back to Basics: C++ Move Semantics - Andreas Fertig - CppCon 2022
https://github.com/CppCon/CppCon2022
Move semantics is a topic that feels hard to understand. This talk will give you a good understanding, demystifying some myths out there using a new and unique way of talking about moving.
For example, you've heard those move operations should be noexcept. In this talk, you will learn the why while we write things like an efficient move constructor and a move assignment operator.
During this talk, we will look at rules for when to use std::move and when to use std::forward.
There is one topic we have to discuss as well, what is a moved-from object, and what can you do with such an object?
You're eager to squeeze out the last drop of performance? Then we should talk about the ref-qualifiers. Why waste performance?
At the end of this talk, you have a solid understanding of move semantics, enabling you to write competitive performant code.
