// Create a BookInfo object and populate it:
var info = BookInfo()
info.id = 1734
info.title = "Really Interesting Book"
info.author = "Jane Smith"

do {
    // Serialize to binary protobuf format:
    let binaryData: Data = try info.serializedData()

    // Deserialize a received Data object from `binaryData`
    let decodedInfo = try BookInfo(serializedData: binaryData)

    // Serialize to JSON format as a Data object
    let jsonData: Data = try info.jsonUTF8Data()

    // Deserialize from JSON format from `jsonData`
    let receivedFromJSON = try BookInfo(jsonUTF8Data: jsonData)
} catch {
    print(error)
