Enum DataContractConfig 

pub enum DataContractConfig {
    V0(DataContractConfigV0),
    V1(DataContractConfigV1),
    V2(DataContractConfigV2),
}

Variants

V0(DataContractConfigV0)

V1(DataContractConfigV1)

V2(DataContractConfigV2)

Protocol version 14: V1 plus the optional contract moderation declaration.

Implementations

impl DataContractConfig

pub fn validate_update( &self, new_config: &DataContractConfig, contract_id: Identifier, platform_version: &PlatformVersion, ) -> Result<SimpleConsensusValidationResult, ProtocolError>

impl DataContractConfig

pub fn version(&self) -> u16

pub fn default_for_version( platform_version: &PlatformVersion, ) -> Result<DataContractConfig, ProtocolError>

pub fn with_moderation( self, moderation: Option<ContractModerationConfig>, ) -> Self

The same config declaring moderation, raised to V2 when it is lower. A V0 config keeps V0’s defaults for the V1 fields.

pub fn ensure_admitted_by_platform_version( &self, platform_version: &PlatformVersion, ) -> Result<(), ProtocolError>

Refuses a config that declares moderation where the platform version cannot carry the declaration (before protocol version 14). Lowering it would quietly store an unmoderated contract, and moderation can never be turned on by an update.

pub fn config_valid_for_platform_version( self, platform_version: &PlatformVersion, ) -> DataContractConfig

Adjusts the current DataContractConfig to be valid for the provided platform version.

The config version follows the platform version, never the config’s content: a config is lowered only where the platform version does not admit it (V1 to V0 below protocol version 9, V2 to V1 below protocol version 14). From protocol version 14 every new contract carries a V2 config, moderated or not. Lowering a V2 would drop a moderation declaration, so a contract is only serialized once ensure_admitted_by_platform_version has refused that case. Consensus never sees it either way: a contract create or update carrying a V2 config is inactive before protocol version 14 (StateTransition::active_version_range).

pub fn from_value( value: Value, platform_version: &PlatformVersion, ) -> Result<DataContractConfig, ProtocolError>

KEEP-AS-EXCEPTION in the JSON/Value canonical-trait migration — this is a context-aware constructor, not a parallel conversion path: it dispatches the config variant on platform_version (the input map carries no $formatVersion tag in the contract-creation flow), so canonical ValueConvertible::from_object cannot replace it.
