Struct AttributeBackfillPlan 

pub struct AttributeBackfillPlan { /* private fields */ }

First closed binding-neutral data plan: copy one historical attribute.

Implementations

impl AttributeBackfillPlan

pub fn new( owner: TypeId, source: AttributeId, destination: AttributeId, partition: BackfillPartition, managed_semantics: ManagedSemanticSchemaFingerprint, reverse: Option<BackfillReverseProgram>, ) -> Result<Self, Diagnostic>

Construct and validate an exact copy-attribute data plan.

pub const fn owner(&self) -> &TypeId

Return the historical owner type selected by this plan.

pub const fn source(&self) -> &AttributeId

Return the historical source attribute.

pub const fn destination(&self) -> &AttributeId

Return the historical destination attribute.

pub const fn partition(&self) -> &BackfillPartition

Return deterministic transaction partitioning.

pub const fn managed_semantics(&self) -> &ManagedSemanticSchemaFingerprint

Return the exact historical intermediate-schema fingerprint.

pub const fn conflict(&self) -> BackfillConflictPolicy

Return the fixed conflict policy.

pub const fn transform(&self) -> BackfillValueTransform

Return the fixed value transformation.

pub const fn postcondition(&self) -> BackfillPostcondition

Return the required terminal postcondition.

pub const fn reverse(&self) -> Option<BackfillReverseProgram>

Return the optional checked reverse program.

pub const fn required_capabilities(&self) -> &CapabilitySet

Return capabilities derived from the closed plan variant.

pub fn canonical_bytes(&self) -> Result<Vec<u8>, Diagnostic>

Return exact canonical plan bytes.

pub fn fingerprint(&self) -> Result<Fingerprint, Diagnostic>

Compute the domain-separated plan fingerprint.
