I created you and I will cancel you. Understanding how to work with coroutine cancellations

As part of the lecture, we will deal with such a phenomenon as the cancellation of coroutines. We will try to understand in what cases it may be necessary to cancel a working coroutine manually, how to do it correctly, and also how to catch the moment of cancellation itself. The talk is aimed at those who are already familiar with the work of coroutines but want to understand how certain aspects of working with them are arranged under the hood.
