FieldSnapshotEnvelopeV2

Struct FieldSnapshotEnvelopeV2 

pub struct FieldSnapshotEnvelopeV2 { /* private fields */ }
Description

Logical snapshot of one Semantic Field in one spatial Realization.

Numerical values stay in normalized DiscreteFieldEnvelopeV1 leaves. A P1 Field has one vertex block; a simplex P1-bubble Field has a vertex block and a top-cell bubble block. Coefficients outside the closure of the Field’s Domain are stored as +0.0, so every block keeps the canonical mesh entity order while the support is still exactly the Domain.

Implementations§

§

impl FieldSnapshotEnvelopeV2

Signature links:§FieldSnapshotEnvelopeV2

pub fn new_moving<M>( context: &ValidatedMovingSpatialContext<'_, M>, field: Id<Field>, blocks: &[DiscreteFieldEnvelopeV1], ) -> Result<FieldSnapshotEnvelopeV2, Diagnostic>
where M: ReplayableCanonicalModelArtifact,

Signature links:new_movingValidatedMovingSpatialContextIdFieldDiscreteFieldEnvelopeV1ResultFieldSnapshotEnvelopeV2DiagnosticReplayableCanonicalModelArtifact

Bind normalized coefficient blocks in a fixed-topology moving context.

Geometry motion changes the enclosing state lineage, not the reference-mesh coefficient representation.

§Errors

Returns EQ0901 when the ALE Realization, immutable reference topology, semantic Field, and normalized coefficient blocks disagree.

pub fn from_json( bytes: &[u8], limits: FieldDecoderLimits, ) -> Result<FieldSnapshotEnvelopeV2, Diagnostic>

Signature links:from_jsonu8FieldDecoderLimitsResultFieldSnapshotEnvelopeV2Diagnostic

Decode the closed logical manifest without resolving referenced blocks.

§Errors

Returns EQ0901 for malformed, oversized, noncanonical, or unsupported wire data.

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

Signature links:canonical_jsonResultVecu8Diagnostic

Deterministic canonical JSON bytes.

§Errors

Returns EQ0901 if serialization unexpectedly fails.

pub fn digest(&self) -> Result<ArtifactDigest, Diagnostic>

Signature links:digestResultArtifactDigestDiagnostic

Domain-separated logical identity of meaning and normalized block content.

§Errors

Returns EQ0901 if canonical serialization fails.

pub fn model_artifact(&self) -> ArtifactDigest

Signature links:model_artifactArtifactDigest

Semantic Model artifact.

pub fn realization_artifact(&self) -> ArtifactDigest

Signature links:realization_artifactArtifactDigest

Realization artifact.

pub fn geometry_artifact(&self) -> ArtifactDigest

Signature links:geometry_artifactArtifactDigest

Geometry revision.

pub fn correspondence_artifact(&self) -> ArtifactDigest

Signature links:correspondence_artifactArtifactDigest

Geometry-to-mesh correspondence.

pub fn mesh_artifact(&self) -> ArtifactDigest

Signature links:mesh_artifactArtifactDigest

Mesh revision.

pub fn field(&self) -> Id<Field>

Signature links:fieldIdField

Semantic Field identity.

pub fn support_domain(&self) -> Id<Domain>

Signature links:support_domainIdDomain

Volume Domain on which the Field is supported.

pub const fn dimension(&self) -> DimExponents

Signature links:dimensionDimExponents

Physical dimension in coherent SI base units.

pub fn value_shape(&self) -> ValueShape

Signature links:value_shapeValueShape

Mathematical value shape.

pub const fn frame(&self) -> ValueFrame

Signature links:frameValueFrame

Coordinate-frame meaning of components.

pub fn block_artifacts(&self) -> Vec<(DiscreteFieldAssociation, ArtifactDigest)>

Signature links:block_artifactsVecDiscreteFieldAssociationArtifactDigest

Canonically ordered normalized coefficient-block identities.

pub fn validate_against_moving<'a, M>( &self, context: &ValidatedMovingSpatialContext<'_, M>, blocks: impl IntoIterator<Item = &'a DiscreteFieldEnvelopeV1>, ) -> Result<(), Diagnostic>
where M: ReplayableCanonicalModelArtifact,

Signature links:validate_against_movingValidatedMovingSpatialContextIntoIteratorDiscreteFieldEnvelopeV1Result()DiagnosticReplayableCanonicalModelArtifact

Rebuild and compare this logical snapshot in a moving context.

§Errors

Returns EQ0901 for any semantic, ALE resource, block, or content drift.

pub fn active_entities_against_moving<M>( &self, context: &ValidatedMovingSpatialContext<'_, M>, association: DiscreteFieldAssociation, ) -> Result<Vec<usize>, Diagnostic>
where M: ReplayableCanonicalModelArtifact,

Signature links:active_entities_against_movingValidatedMovingSpatialContextDiscreteFieldAssociationResultVecusizeDiagnosticReplayableCanonicalModelArtifact

Derive the active mesh entities for one coefficient association.

This operation revalidates the snapshot’s semantic and moving-spatial lineage. Returned indices are sorted in canonical reference-mesh order; they never imply identity across mesh revisions.

§Errors

Returns EQ0901 for stale snapshot lineage, an association absent from the snapshot, or invalid support incidence.

pub fn active_entity_count_against_moving<M>( &self, context: &ValidatedMovingSpatialContext<'_, M>, association: DiscreteFieldAssociation, ) -> Result<usize, Diagnostic>
where M: ReplayableCanonicalModelArtifact,

Signature links:active_entity_count_against_movingValidatedMovingSpatialContextDiscreteFieldAssociationResultusizeDiagnosticReplayableCanonicalModelArtifact

Count active entities without allocating their materialized usize index list.

This is the preflight counterpart of Self::active_entities_against_moving.

§Errors

Returns EQ0901 under the same lineage and support conditions as the materializing operation.
