Now that we have co_yield working and understand how it works we should be able to quite easily convert our generator to provide iterators so it acts like a normal C++ collection (or range if you're following the ranges TS work).. int main() { for ( auto v : count() ) std::cout << ">> " << v << std::endl; return 0; } The refactoring is pretty much a matter of just moving code around, but there

That's even worse than described in the problem. Also, maxiumum optimization was applied ( /O2 ) on a Ryzen 7 3700X. In addition to being able to co_yield a value of type T you can also co_yield a value of type recursive_generator. So when you co_yield a recursive_generator value, all elements of the yielded generator are yielded as elements of the current generator. This simplifies the code above as there is no need for the internal range-for loops. layout: true

I would also like to know where noex Passing generator. Usually there are 3 ways to pass generators. const generator &_prev. We use this if we want to use immediate objects without variables and to avoid copying them. Since generator#begin() modifies the generator object, we cannot use method. generator &_prev co_yield is actually very similar to our co_return example previously. There is really just one additional component, and one small change: Because our generator doesn't have any sort of return value there is an implicit return that produces nothing.

A very simple example of unique_generator with co_yield. generator_as_viewable_range.cpp. Similar to generate_ints.cpp, this example demonstrates mixing Coroutines with Ranges. It uses shared_generator (which models ranges::viewable_range) and pipes the generator object through rv::take(10). mcnellis_generator.cpp
