USTRUCT ()  
struct FFastArraySerializer

Base struct for wrapping the array used in Fast TArray Replication

Type	Name	Description
int32	ArrayReplicationKey	Counter used to track array replication.
TMap< int32, FFastArraySerializerGuidReferences >	GuidReferencesMap	List of items that need to be re-serialized when the referenced objects are mapped
TMap< int32, FGuidReferencesMap >	GuidReferencesMap_StructDelta	List of items that need to be re-serialized when the referenced objects are mapped.
int32	IDCounter	Counter used to assign IDs to new elements.
TMap< int32, int32 >	ItemMap	Maps Element ReplicationID to Array Index.

	Type	Name	Description
		FFastArraySerializer ()

	Type	Name	Description
		~FFastArraySerializer ()

Type	Name	Description
bool	FastArrayDeltaSerialize ( TArray< Type >& Items, FNetDeltaSerializeInfo& Parms, SerializerType& ArraySerializer )	Performs "standard" delta serialization on the items in the FastArraySerializer.
const EFastArraySerializerDeltaFlags	GetDeltaSerializationFlags ()
const int32	GetMaxNumberOfAllowedChangesPerUpdate ()
const int32	GetMaxNumberOfAllowedDeletionsPerUpdate ()
void	IncrementArrayReplicationKey ()
void	MarkArrayDirty ()	This must be called if you just remove something from the array
void	MarkItemDirty ( FFastArraySerializerItem& Item )	This must be called if you add or change an item in the array
void	PostReplicatedAdd ( const TArrayView< int32 >& AddedIndices, int32 FinalSize )	Called after adding all new elements and after the elements themselves are notified.
void	PostReplicatedChange ( const TArrayView< int32 >& ChangedIndices, int32 FinalSize )	Called after updating all existing elements with new data and after the elements themselves are notified.
void	PreReplicatedRemove ( const TArrayView< int32 >& RemovedIndices, int32 FinalSize )	Called before removing elements and after the elements themselves are notified.
void	SetDeltaSerializationEnabled ( const bool bEnabled )
bool	ShouldWriteFastArrayItem ( const Type& Item, const bool bIsWritingOnClient )	Helper function for FastArrayDeltaSerialize to consolidate the logic of whether to consider writing an item in a fast TArray during network serialization.

	Type	Name	Description
	CPostReplicatedReceiveFuncable	Concept used to detect if PostReplicatedReceive is defined or not.
	FPostReplicatedReceiveParameters	If a function with the signature void PostReplicatedReceive(const FFastArraySerializer::FPostReplicatedReceiveParameters& Parameters) is defined in the derived struct It will be called after each call to NetDeltaSerialize on the receiving end, including if we have mapped some unmapped objects
