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.

Helper classes

is_error_code_enum<std::future_errc> (C++11)

extends the type trait std::is_error_code_enum to identify future error codes (class template)

Non-member functions

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