(dal C++11)

The scoped enumeration std::future_errc defines the error codes reported by std::future and related classes in std::future_error exception objects. Only four error codes are required, although the implementation may define additional error codes. Because the appropriate specialization of std::is_error_code_enum is provided, values of type std::future_errc are implicitly convertible to std::error_code.

Explanation
broken_promise the asynchronous task abandoned its shared state
future_already_retrieved the contents of shared state were already accessed through std::future
promise_already_satisfied attempt to store a value in the shared state twice
no_state attempt to access std::promise or std::future without an associated shared state
