Building Custom Task Types with C++ Coroutines

C++ Coroutines unlock powerful asynchronous patterns, but understanding how to wrap them into reusable Task types is essential for writing production-ready concurrent code. This course guides you through the process of designing the fundamental promise_type and Task wrapper necessary to manage coroutine state, suspension, and resumption safely, preparing you to write high-performance asynchronous applications. What you'll learn: * Understand the core components of C++ Coroutines: promises, handles, and initial/final suspend points. * Design and implement custom Task types capable of handling both value-returning and void-returning coroutines. * Practice managing coroutine lifetime and ensuring safe resource cleanup using modern C++ principles. * Apply key concepts like the Awaitable pattern and the co_await mechanism for controlling execution flow. * Configure coroutine resumption logic to integrate custom execution contexts for non-blocking operations. The material starts with foundational definitions and the coroutine lifecycle, then moves into the practical implementation of the required types. You will build a complete, working Task type from scratch, focusing on the underlying mechanisms of suspension and resumption. This course is ideal for intermediate C++ programmers who are new to the C++20 Coroutines feature and want to deeply understand how asynchronous libraries are constructed. No prior experience with coroutines is needed. Start mastering the building blocks of C++ concurrency today.
