Fields

max_serialized_size: u32

The maximum that we can store a data contract in the state. There is a possibility that a client sends a state transition serialized in a specific version and that the system re-serializes it to the current version, and in so doing increases it’s size.

contract_serialization_version: FeatureVersionBounds

This is how we serialize and deserialize a contract

contract_storage_serialization_version: u16

The format a node stores a contract in: the DataContractInSerializationFormat variant Drive writes to state. It is a separate selector because a stored format need not be one that state transitions carry or clients are sent. Each protocol version so far selects the format of contract_serialization_version’s default; format 2, the stored format with compiled document types, is written only from the protocol version whose table selects it.

contract_storage_document_type_version: u16

The generation of a document type’s stored form (DocumentTypeInSerializationFormat) that a contract stored in format 2 holds each of its document types in. The stored form carries its generation, so changing this changes only what is written from then on; a generation is paired with the builders whose output it stores, so one that rebuilds an index structure on load (generation 0 rebuilds it with index_levels_from_indices 0) is selected only with them.

contract_structure_version: u16

This is the structure of the Contract as it is defined for code paths
