std::future_error

Member functions

future_error::future_error

future_error::code

future_error::what

 

explicit future_error( std::future_errc ec );		(since C++17)

Constructs a new future error object containing the error code std::make_error_code(ec).

Parameters

ec

-

error code

Notes

There is no standard-compliant way for the user to construct a future_error prior to C++17. C++11 and C++14 depict an exposition-only public constructor taking a std::error_code, and some implementations provide such a constructor.
