Rvalue references are one of those features in C++ that can feel a bit complex at first. They play a crucial role in the efficiency of modern C++ code, especially when it comes to resource management.
If you're coming off the chapter on move semantics, you're already familiar with the motivation behind wanting to optimize resource handling. Rvalue references are a foundational building block that allows us to achieve this optimization.
So, let’s dive into rvalue references, explore their syntax, practical applications, and some common pitfalls. By the end, you’ll see how they work hand in hand with move semantics to elevate your C++ programming skills.
