< cpp‎ | error‎ | 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.
