TPolymorphicStructNetSerializerImpl

Helper to implement serializers that requires dynamic polymorphism. It can either be used to declare a typed serializer or be used as an internal helper. ExternalSourceType is the class/struct that has the TSharedPtr data. ExternalSourceItemType is the polymorphic struct type GetItem is a function that will return a reference to the TSharedPtr

!BIG DISCLAIMER:!

This serializer was written to mimic the behavior seen in FGameplayAbilityTargetDataHandle and FGameplayEffectContextHandle which both are written with the intent of being used for RPCs and not being used for replicated properties and uses a TSharedPointer to hold the polymorphic struct

That said, IF the serializer is used for replicated properties it has very specific requirements on the implementation of the SourceType to work correctly.

The sourcetype MUST provide a custom assignment operator performing a deep-copy/clone

The sourcetype MUST define a comparison operator that compares the instance data of the stored ExternalSourceItemType

TStructOpsTypeTraits::WithCopy and TStructOpsTypeTraits::WithIdenticalViaEquality must be specified

Syntax

template<typename ExternalSourceType, typename ExternalSourceItemType, TSharedPtr < ExternalSourceItemType > & GetItem>  
struct TPolymorphicStructNetSerializerImpl : protected UE::Net::Private::FPolymorphicStructNetSerializerInternal
