In the following example @ValueSet is used to fetch the protocol type name
based on an id read in by the binary definition.
The protocol_name will just appear when the object is serialized and will
gave the object more context.
const ID_TO_NAME = {
1: "Record",
...
}
class Protocol {
@Relation(PrimitiveSymbol.u8)
protocol_id: number
@ValueSet(_ => ID_TO_NAME[_.protocol_id] || 'UNKNOWN')
protocol_name: string
}
