std::error_condition::operator=(3) C++ Standard Libary std::error_condition::operator=(3)


std::error_condition::operator= - std::error_condition::operator=


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

Assigns contents to an error condition.

1) Copy assignment operator. Assigns the contents of other.
2) Assigns error condition for enum e. Effectively calls make_error_condition found
by argument-dependent lookup for e. This overload participates in overload
resolution only if std::is_error_condition_enum<ErrorConditionEnum>::value is true.


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


The ADL-found make_error_condition is intended to be used in the original proposal
N2422, and used by all known implementations. However, the standard requires that
only std::make_error_condition overloads are considered. This is LWG issue 3629.
