std::experimental::future
| Defined in header <experimental/future> | ||
|---|---|---|
| template< class T > class future; | (1) | (concurrency TS) |
| template< class T > class future<T&>; | (2) | (concurrency TS) |
| template<> class future<void>; | (3) | (concurrency TS) |
The class template std::experimental::future extends std::future with the following operations:
- an unwrapping constructor from
future<future<T>>; - a member function
is_readyto query whether the associated shared state is ready; and - a member function
thento attach a continuation to the future.
However, there is no interoperation between std::experimental::future and std::future.
