Overview of this book

C++ High Performance, Second Edition guides you through optimizing the performance of your C++ apps. This allows them to run faster and consume fewer resources on the device they're running on without compromising the readability of your codebase. The book begins by introducing the C++ language and some of its modern concepts in brief. Once you are familiar with the fundamentals, you will be ready to measure, identify, and eradicate bottlenecks in your C++ codebase. By following this process, you will gradually improve your style of writing code. The book then explores data structure optimization, memory management, and how it can be used efficiently concerning CPU caches. After laying the foundation, the book trains you to leverage algorithms, ranges, and containers from the standard library to achieve faster execution, write readable code, and use customized iterators. It provides hands-on examples of C++ metaprogramming, coroutines, reflection to reduce boilerplate code, proxy objects to perform optimizations under the hood, concurrent programming, and lock-free data structures. The book concludes with an overview of parallel algorithms. By the end of this book, you will have the ability to use every tool as needed to boost the efficiency of your C++ projects.

Asynchronous Programming with Coroutines

The generator class implemented in the previous chapter helped us to use coroutines for building lazily evaluated sequences. C++ coroutines can also be used for asynchronous programming by having a coroutine represent an asynchronous computation or an asynchronous task. Although asynchronous programming is the most important driver for having coroutines in C++, there is no support for asynchronous tasks based on coroutines in the standard library. If you want to use coroutines for asynchronous programming, I recommend you find and use a library that complements C++20 coroutines. I've already recommended CppCoro (https://github.com/lewissbaker/cppcoro), which at the time of writing seems like the most promising alternative. It's also possible to use asynchronous coroutines with the well-established library Boost.Asio, as you will see later on in this chapter.

This chapter will show that asynchronous programming is possible using...
