POLO Serialization

POLO (Prefix Ordered Lookup Offsets) is MOI's binary encoding scheme with deterministic serialization, minimal wire size, and serialization safety.

Functions​

FunctionDescription
polorize(value)Serialize any value → Bytes
depolorize(Type, bytes)Deserialize bytes → specified type

Example​

coco SerializationExample

endpoint pure Serialize(name String) -> (data Bytes):
    data = polorize(name)

endpoint pure Deserialize(data Bytes) -> (name String):
    name = depolorize(String, data)

Usage Notes​

  • POLO produces deterministic output, even for maps
  • Optimized for partial decoding and differential messaging
  • Used internally by MOI for all data encoding
tip

For most Coco development, you won't need to use POLO directly — it's handled automatically by the runtime.
