Yes, that's even more clear like that :-)
And for Encodable support, it works just great (not a single line of
boilerplate code):
private enum Color: String, DatabaseValueConvertible, Encodable {
case red, green, blue
}
private struct EncodableStruct : Persistable, Encodable {
static let databaseTableName = "myTable"
let name: String
let color: Color?
}
try dbQueue.inDatabase { db in
try EncodableStruct(name: "Arthur", color: .red).insert(db)
}
