WebImplementations that produce sequences of values typically use asymmetric coroutines. [5] stackful. Each instance of a coroutine has its own stack. In contrast to stackless coroutines, stackful coroutines allow invoking the suspend operation out of arbitrary sub-stackframes, enabling escape-and-reenter recursive operations. move-only WebStackless Coroutines The coroutine class provides support for stackless coroutines.

WebA std::coroutine_handle for any type T can be implicitly converted to a std::coroutine_handle.Either type can be invoked to resume the coroutine with the same effect. However, the non-void types allow you to convert back and forth between a coroutine handle and the promise_type sitting in the coroutine state. Specifically, within … WebAfter years of work, the C++ standard is finally close to adding basic support for stackful coroutines in C++26 (see P0876). It’s worth delving further into stackful vs. stackless coroutines.
