error_condition( error_condition&& other)=default;	(5)	(since C++11) (implicitly declared)

Constructs new error condition.

1) Default constructor. Initializes the error condition with generic category and error value0.

2) Initializes the error condition with error valueval and error categorycat.

3) Initializes the error condition with enume. Effectively callsmake_error_condition that is only found byargument-dependent lookup fore. This overload participates in overload resolution only ifstd::is_error_condition_enum<ErrorConditionEnum>::value istrue.

4,5) Implicitly defined copy constructor and move constructor. Initializes the error condition with the contents of theother.

[edit]Parameters

other	-	another error condition to initialize with
val	-	error value
cat	-	error category
e	-	error condition enum

[edit]Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
LWG 3629	C++11	only`std::make_error_condition` overloads were used	ADL-found overloads are used
