C++20’s Coroutines for Beginners - Andreas Fertig - CppCon 2022

C++20 coroutines explained for beginners, covering co-routines, cooperative multitasking, and customization points, with real-world examples of parsing data streams, scheduling, and more.

Key takeaways

C++20 coroutines are a way to write asynchronous code that is easier to read and maintain than traditional callback-based code.
Coroutines are essentially co-routines, allowing for cooperative multitasking.
The author uses a simple example of a coroutine that prints numbers, demonstrating how to use co_yield, co_wait, and co_return.
The author also discusses other customization points such as initial_suspend, pending, and final_suspend.
Coroutines can be used for cooperative multitasking, replacing traditional threading models.
The author demonstrates how to implement a simple scheduler that allows for coroutine scheduling.
Coroutines can also be used for parsing data streams, making it easier to write readable and maintainable code.
The author discusses how to implement a generator using coroutines, allowing for efficient and readable code.
Coroutines can also be used for operating system-level programming, allowing for efficient and readable code.
The author discusses how to use coroutines with lambda functions, allowing for more concise code.
The author also discusses the use of coroutines with vectors, allowing for efficient and readable code.
Coroutines can also be used for parsing data streams, making it easier to write readable and maintainable code.
The author discusses how to implement a coroutine that can be suspended and resumed, allowing for cooperative multitasking.
