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.


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

Return value
