Review Comment:
> I find that for de/serialize, we need the type info. Maybe using Struct
with StructType here is more appropriate. (For now, Datum doesn't support
Struct). So that we can convert it between RawLiteral directly.
We may have many manifests, and storing a struct type may increase memory
usage slightly, but it doesn't seem a blocker
