`WithCopy`是什么

当属性发生变化时候, 怎么赋值. 即实现operator =操作函数重载.

自定义结构体指定`WithCopy`

USTRUCT()
struct FTestNetSerializeSharedPtrContainer
{
    GENERATED_USTRUCT_BODY()

    uint32 CounterUniqueID = 0;
    TSharedPtr<FTestNetSerializeSharedPtrBase> Data;

    /** Serialize the root motion sources and their states for this group */
    bool NetSerialize(FArchive& Ar, UPackageMap* Map, bool& bOutSuccess);

    bool Identical(const FTestNetSerializeSharedPtrContainer* Other, uint32 PortFlags) const;
    bool operator==(const FTestNetSerializeSharedPtrContainer &Other) const;
    bool operator!=(const FTestNetSerializeSharedPtrContainer& Other) const;
    FTestNetSerializeSharedPtrContainer& operator=(const FTestNetSerializeSharedPtrContainer& Other);

    void AddStructReferencedObjects(class FReferenceCollector& Collector);
};

template<>
struct TStructOpsTypeTraits< FTestNetSerializeSharedPtrContainer > : public TStructOpsTypeTraitsBase2< FTestNetSerializeSharedPtrContainer >
{
    enum
    {
        WithNetSerializer = true,
        WithIdenticalViaEquality = true,
        WithCopy = true,
        WithAddStructReferencedObjects = true
    };
};
