std::error_condition
template < class ErrorConditionEnum >
error_condition& operator= ( ErrorConditionEnum e ) noexcept ;
(1) (since C++11)
error_condition& operator= ( const error_condition& other ) = default ;
(2) (since C++11)
(implicitly declared)
error_condition& operator= ( error_condition&& other ) = default ;
(3) (since C++11)
(implicitly declared)

Assigns contents to an error condition.

1) Assigns error condition for enum e. Effectively calls make_error_condition that is only found by argument-dependent lookup for e and then replaces *this with the result. This overload participates in overload resolution only if std::is_error_condition_enum <ErrorConditionEnum> :: value is true
2,3) Implicitly defined copy-assignment operator and move-assignment operator assign the contents of other to *this

Parameters

e - error condition enum
other - another error condition to assign with

Return value

*this.
