Struct Unit 

pub struct Unit;

The Daml Unit type. Its LF-JSON form is the empty object {} — not JSON null, which is what Rust’s () serializes to — so Unit needs its own type with a manual serde impl. This is what a nullary variant constructor and a Unit-typed field map to, so their JSON matches the Ledger API’s {"tag": <ctor>, "value": {}} form. The gRPC (Value) form is the proto Unit.
