As long as you’re changing your code you might want to migrate from using `await` to `co_await` and from `return` in a coroutine to `co_return`. Contribute to microsoft/clang development by creating an account on GitHub. …keywords.

Three new language keywords: co_await, co_yield and co_return; Several new types in the std::experimental namespace: coroutine_handle

coroutine_traits suspend_always; suspend_never; A general mechanism that library writers can use to interact with coroutines and customise their behaviour.

Atypicalexampleof `yield` keyword to become `co_yield` in VS 2017 EricMittelette January 27, 2017 Jan 27, 2017 01/27/17 Coroutines—formerly known as “C++ resumable functions”—are one of the Technical Specifications (TS) that we have implemented in the Visual C++ compiler. A yield co or yieldco is a company that is formed to own operating assets that produce a predictable cash flow, primarily through long term contracts. Separating volatile activities (such as development, R&D, construction) from stable activities of operating assets can lower the cost of capital Yield cos are expected to pay a major portion of their earnings in dividends, which may be a Re-write IFN_CO_YIELD, deferred to post-LTO (this was expected to produce the best opportunities for optimisation, but it's a CHECK-ME to compare pre and post). This rewrites the actor function so that the suspend/resume paths are distinct from the destruction ones, allowing the ME optimiser to inline the functionality separately and DCE the unused portions. Admittedly, the program doesn't do something meaningful, but it helps to understand the workflow of coroutines. First of all, the main function can't be a coroutine.

Se hela listan på en.cppreference.com KEYWORD(co_yield , KEYCOROUTINES) // GNU Extensions (in impl-reserved namespace) KEYWORD(_Decimal32 , KEYALL) KEYWORD(_Decimal64 , KEYALL) The appearance of the co_yield keyword identifies the function hello as a coroutine. Use of the co_yield keyword allows the coroutine to suspend and deliver an intermediate result to the caller. Since the type of the expression *p++ is char const& , it might not be immediately clear how this value interacts with the return type of the function to give the loop in main a value.

co_yield expression expression allows it to write a generator function. The generator function returns a new value each time. A generator function is a kind of data stream from which you can pick values. The data stream can be infinite. Consequentially, we are in the center of lazy evaluation. When a compiler encounters co_await, co_yield or co_return in a function, it treats the function as a coroutine.

However, the specific case is a useful one, namely returning values from coroutines. uses the keyword co_yield to suspend execution returning a value generator < int > iota ( int n = 0 ) { while ( true ) co_yield n ++ ; } uses the keyword co_return to complete execution returning a value The Coroutines TS adds three new keywords: co_await, co_yieldand co_return. of these coroutine keywords in the body of a function this triggers the compiler to compile this function as a coroutine rather than as a normal function.
