operator<<(typename UE::Core::Private::TAlwaysFArchive< TVariant< Ts... > >::Type &, TVariant< Ts... > &)

Description

Serialization function for TVariants.

In order for a TVariant to be serializable, each type in its template parameter pack must:

Have a default constructor. This is required because when reading the type from an archive, it must be default constructed before being loaded.

Implement the `FArchive& operator<<(FArchive&, T&)_ function. This is required to serialize the actual type that's stored in TVariant.
