std::future_error::future_error
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.
