The generator function returns on request each time a new value. A generator function is a kind of data stream, from which you can pick values. The data stream can be infinite; therefore, we are in the centre of lazy evaluation with C++. co_yield expression expression allows it to write a generator function. The generator function returns a new value each time.

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.

Abstract; Introduction; Coroutines TS; References; Acknowledgements; Listing 1; Listing 2. Abstract. Coroutines enable authors to write code which may be suspended and resumed at well defined locations without inverting the flow of control. 2, to simultaneously obtain high CO yield and energy efficiency. This can be done by quickly quenching the decomposed gas or rapidly taking away free oxygen from decomposed gas.

It uses shared_generator (which models ranges::viewable_range) and pipes the generator object through rv::take(10). mcnellis_generator.cpp For example: co_yield i + 1; Here after inserting co_yield the expression is passed to InsertArg which does the rest of the job. The same goes for CoreturnStmt. Handling the CoroutineBodyStmt comes with opening a scope and inserting the data there.
