enum class future_status {
ready,
timeout,
deferred
};
| (since C++11) |
Specifies state of a future as returned by wait_for and wait_until functions of std::future and std::shared_future.
| Constant | Explanation |
|---|---|
deferred | the shared state contains a deferred function, so the result will be computed only when explicitly requested |
ready | the shared state is ready |
timeout | the shared state did not become ready before specified timeout duration has passed |
| waits for the result, returns if it is not available for the specified timeout duration (public member function of std::future<T>) |
|
| waits for the result, returns if it is not available for the specified timeout duration (public member function of std::shared_future<T>) |
|
| waits for the result, returns if it is not available until specified time point has been reached (public member function of std::future<T>) |
|
| waits for the result, returns if it is not available until specified time point has been reached (public member function of std::shared_future<T>) |
