enumclass future_errc {     broken_promise,     future_already_retrieved,     promise_already_satisfied,     no_state };		(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.

Membri costanti

Constant Original: Constant The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions.	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

Helper classi

is_error_code_enum<std::future_errc> (C++11)	extends the type trait std::is_error_code_enum to identify future error codes (classe template)

Non membri funzioni

make_error_code(std::future_errc) (C++11)	constructs a future error code (funzione)
make_error_condition(std::future_errc) (C++11)	constructs a future error_condition (funzione)
