Advantages of stop_token

The advantages of using stop_token are as follows:

• Efficient and lightweight: It provides a lightweight and efficient way of canceling asynchronous operations. The std::stop_token class is lightweight and can be copied and moved efficiently.
• More elegant and thread-safe: It avoids the need for manual cancellation flags and provides a more elegant and thread-safe way of canceling operations. This makes it easier to write robust and efficient code.
• Interoperability: It is designed to be interoperable with other C++20 concurrency features such as coroutines and futures. This makes it easier to write complex concurrent programs.
• Scalable and flexible: It is scalable and flexible, making it suitable for a wide range of applications, from simple programs to complex systems. It allows for fine-grained control over the cancellation of asynchronous operations.
• Standardized: It is part of the C++20 standard library, which means that it is widely available and supported by many compilers and tools.

C++20 has introduced the <stop_token> Header, presenting an alternative method for canceling asynchronous operations. A new class std::stop_token is provided by the <stop_token> header that allows for seamless communication of a termination request between two threads.

In this article, we will discuss the basics of <stop_token> and how to use it in C++20.
