template< class ErrorCodeEnum >
error_code& operator=( ErrorCodeEnum e ) noexcept;
(since C++11)

Replaces the error code and corresponding category with those representing error code enum e.

Equivalent to *this = make_error_code(e), where make_error_code is called unqualified to enable argument-dependent lookup. This overload participates in overload resolution only if std::is_error_code_enum<ErrorCodeEnum>::value is true.


[edit] Parameters

e - error code enum to construct

[edit] Return value


[edit] Notes

Copy-assignment operator is defined implicitly.

The ADL-found make_error_code 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_code overloads are considered. This is LWG issue 3629.
