Enum DataType 

#[non_exhaustive]
pub enum DataType {
    Record(Record),
    Variant(Variant),
    Enum(Enum),
    InterfaceMarker(String),
}

A named data type declared in a module: a record, a variant, or an enum.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Record(Record)

A record (product) type.

Variant(Variant)

A variant (sum) type.

Enum(Enum)

An enumeration (constructors carrying no payload).

InterfaceMarker(String)

An interface marker: a phantom tag emitted so references to the interface (always ContractId<I>) resolve. The interface itself is not serializable and carries no data of its own — its view and choices are emitted separately, from Interface. The String is the name.
