Serialized result sets contain a short signature which can't be forged or replayed across different game sessions. A result set can be serialized on the local client, transmitted to other players via your game networking, and deserialized by the remote players.This is a secure way of preventing hackers from lying about posessing rare/high-value items. Serializes a result set with signature bytes to an output buffer.The size of a serialized result depends on the number items which are being serialized.When securely transmitting items to other players, it is recommended to use GetItemsByID first to create a minimal result set. Results have a built-in timestamp which will be considered "expired" after an hour has elapsed.See DeserializeResult for expiration handling.
