String ucb_encode(DValue value)

Serializes a DValue to UCEB1, UCE's binary DValue wire format for the WASM membrane and future cross-instance calls.

UCEB1 is length-prefixed and binary-safe. It preserves nested maps, list-shaped maps, empty lists, and scalar bytes, including embedded NUL bytes. Use JSON/YAML/XML serializers for human-facing formats; use UCEB1 when UCE code needs the native DValue protocol.

Example

DValue original;
original["msg"] = "hello";
String packed = ucb_encode(original);
print("encoded ", packed.length(), " bytes; round-trips to: ", ucb_decode(packed)["msg"].to_string(), "\n");

Output

encoded 22 bytes; round-trips to: hello
