Defined in header <future>
class future_error;		(since C++11)

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.

Inheritance diagram

Member functions

(constructor)	creates a std::future_error object (public member function)
code	returns the error code (public member function)
what	returns the explanatory string specific to the error code (public member function)

Inherited from std::logic_error

Inherited from std::exception

Member functions

(destructor) [virtual]	destructs the exception object (virtual public member function of std::exception)
what [virtual]	returns an explanatory string (virtual public member function of std::exception)
