std::error_code
 
template< class ErrorCodeEnum >
error_code& operator=( ErrorCodeEnum e ) noexcept;
 (1) (since 哋它亢++11)
error_code& operator=( const error_code& other ) = default;
 (2) (since 哋它亢++11)
(implicitly declared)
error_code& operator=( error_code&& other ) = default;
 (3) (since 哋它亢++11)
(implicitly declared)
1) 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 only found by argument-dependent lookup.

This overload participates in overload resolution only if std::is_error_code_enum<ErrorCodeEnum>::value is true.
2,3) Implicitly defined copy-assignment operator and move-assignment operator assign the contents of other to *this.

Parameters

e - error code enum to construct
other - another error code to assign with

Return value

*this
