5/// Extension trait that adds CBOR serialization/deserialization capabilities
6/// to any type implementing `PlutusDataJson`.
7///
8/// This trait is implemented automatically for all types that implement `PlutusDataJson`,
9/// allowing direct conversion to/from CBOR hex strings.
10///
11/// # Example
12///
13/// ```rust,ignore
14/// use whisky_csl::PlutusDataCbor;
15/// use whisky::data::PlutusDataJson;
16///
17/// #[derive(Debug, Clone, ConstrEnum)]
18/// pub enum HydraOrderBookIntent {
19///     PlaceOrderIntent(Box<(Order, MValue)>),
20///     ModifyOrderIntent(Box<(Order, MValue)>),
21/// }
22///
23/// // Deserialize from CBOR
24/// let cbor_hex = "d87a9f...";
25/// let intent = HydraOrderBookIntent::from_cbor(cbor_hex)?;
26///
27/// // Serialize back to CBOR
28/// let cbor_out = intent.to_cbor()?;
29/// ```
