Defined in header <future>
class future_error;
(desde C++11)
El std::future_error clase define un objeto de excepción que se produce en caso de fallo de las funciones de la biblioteca de subprocesos que tienen que ver con la ejecución asincrónica y estados compartida (std::future, std::promise, etc). Al igual que std::system_error, esta excepción lleva un código de error compatible con std::error_code .
Original:
The class std::future_error defines an exception object that is thrown on failure by the functions in the thread library that deal with asynchronous execution and shared states (std::future, std::promise, etc). Similar to std::system_error, this exception carries an error code compatible with std::error_code.
