Modern C++ Programming Cookbook

Overview of this book

C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. The latest versions of C++ have seen programmers change the way they code, giving up on the old-fashioned C-style programming and adopting modern C++ instead. Beginning with the modern language features, each recipe addresses a specific problem, with a discussion that explains the solution and offers insight into how it works. You will learn major concepts about the core programming language as well as common tasks faced while building a wide variety of software. You will learn about concepts such as concurrency, performance, meta-programming, lambda expressions, regular expressions, testing, and many more in the form of recipes. These recipes will ensure you can make your applications robust and fast. By the end of the book, you will understand the newer aspects of C++11/14/17 and will be able to overcome tasks that are time-consuming or would break your stride while developing.

Preface

Writing your own type traits


In the previous recipe, we have seen what type traits are, what traits the standard provides, and how they can be used for various purposes. In this recipe, we take a step further and take a look at how to define our own custom traits.

Getting ready

It is recommended that you first read the recipe, Using type traits to query properties of types, before you continue with this one.

In this recipe, we will learn how to solve the following problem: we have several classes that support serialization. Without getting into any details, let's suppose some provide a "plain" serialization to a string (regardless of what that can mean), whereas others do it based on a specified encoding. The end goal is to create a single, uniform API for serializing objects of any of these types. For this, we will consider the following two classes: foo that provides a simple serialization, and bar that provides serialization with encoding:

    struct foo
    {
      std::string serialize...
