Excellent! Glad that ended up working out — looking forward to seeing
this improve quality of life for GRDB users and others. :)

I didn’t know that was possible either! Really cool. Even better:
if let databaseValueType = T.self as? DatabaseValueConvertible.Type
{
let databaseValue: DatabaseValue = row.value(named:
key.stringValue)
return databaseValueType.fromDatabaseValue(databaseValue) as! T
} else { … }
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)
}
