NAME

std::future_error::future_error - std::future_error::future_error

Synopsis

future_error( const future_error& other ) noexcept; (1) (since C++11)
explicit future_error( std::future_errc ec ); (2) (since C++17)

1) Copy constructor. Initializes the contents of the new future_error object with
those of other. If *this and other both have dynamic type std::future_error then
std::strcmp(what(), other.what()) == 0.
2) Constructs a new future_error object containing the error code
std::make_error_code(ec).

Parameters

other - another future_error object to copy
ec - error code

Notes

There is no standard-compliant way for the user to construct a future_error other
than copying from another 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.
