TopologyStateUpdate
Companion object TopologyStateUpdate
final case class TopologyStateUpdate[+Op <: AddRemoveChangeOp] extends TopologyTransaction[Op] with Product with Serializable
+/-, X -> Y
Every topology transaction is the combination of an operation (Add, Remove), a unique element id and the state operation.
An Add can pick a random element id. A remove needs to pick the element id of the corresponding addition. Element ids are uniqueness constraints. Once removed, they can't be re-added (during a configurable time window)

UntypedVersionedMessagewrapper.Subclasses should make this method public by default, as this supports composing proto serializations. Keep it protected, if there are good reasons for it (e.g. com.digitalasset.canton.serialization.ProtocolVersionedMemoizedEvidence).
Be aware that if calling on a class that defines a LegacyProtoConverter, this method will still return a VersionedMessage. If the current protocol version maps to the legacy converter, deserialization will then fail (as it will try to deserialize to the raw protobuf instead of the VersionedMessage wrapper this was serialized to. Prefer using toByteString which handles this use case correctly.

Serializes this instance to a message together with a delimiter (the message length) to the given output stream.
This method works in conjunction with com.digitalasset.canton.version.HasProtocolVersionedCompanion2.parseDelimitedFromUnsafe which deserializes the message again. It is useful for serializing multiple messages to a single output stream through multiple invocations.
Serialization is only supported for com.digitalasset.canton.version.HasSupportedProtoVersions.VersionedProtoConverter, an error message is returned otherwise.
