Implementations

impl CoordinatorDataPlanEnvelope

pub fn from_parts( schema: &DatasetSchema, plan: DataPlan, relations: Option<&SampleRelationTable>, ) -> Result<CoordinatorDataPlanEnvelope, DataError>

pub fn validate(&self) -> Result<(), DataError>

Validate the envelope.

Only the plan fingerprint is recomputed and matched against the declared value (the plan is carried in the envelope), so a tampered plan is rejected with DataError::FingerprintMismatch. The schema and relation fingerprints are replay keys for source artifacts (the DatasetSchema and the source SampleRelationTable) that are not carried here, so they are format-validated only; the embedded coordinator_relations is a derived view validated structurally, not against the fingerprint.

Trait Implementations

impl Clone for CoordinatorDataPlanEnvelope

fn clone(&self) -> CoordinatorDataPlanEnvelope

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CoordinatorDataPlanEnvelope

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CoordinatorDataPlanEnvelope

fn deserialize<__D>( __deserializer: __D, ) -> Result<CoordinatorDataPlanEnvelope, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CoordinatorDataPlanEnvelope

fn eq(&self, other: &CoordinatorDataPlanEnvelope) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CoordinatorDataPlanEnvelope

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
