Struct DiscreteFieldEnvelopeV1 

pub struct DiscreteFieldEnvelopeV1 { /* private fields */ }
Description

Versioned, affine-simplex-mesh-bound discrete field content.

The envelope contains only numerical content identity: exact mesh digest, association, component shape, entity count, and entity-major values. Source names, file locations, storage layout, units, and Semantic Model bindings belong to separate typed contracts.

Decoding validates the closed wire grammar and resource limits, but does not make an independently loaded mesh appear by implication. Call Self::validate_mesh_artifact to obtain the accepted in-memory payload.

Implementations§

§

impl DiscreteFieldEnvelopeV1

Signature links:§DiscreteFieldEnvelopeV1

pub fn from_payload( mesh: &SimplicialMeshEnvelopeV1, payload: &DiscreteFieldPayload, ) -> Result<DiscreteFieldEnvelopeV1, Diagnostic>

Signature links:from_payloadSimplicialMeshEnvelopeV1DiscreteFieldPayloadResultDiscreteFieldEnvelopeV1Diagnostic

Bind an already checked payload to one exact affine-simplex mesh.

The association count is independently rechecked against mesh before bytes are produced.

§Errors

Returns EQ0901 for a mesh-linkage mismatch or a value/count that is not representable by the portable v1 wire contract.

pub fn from_json( bytes: &[u8], limits: FieldDecoderLimits, ) -> Result<DiscreteFieldEnvelopeV1, Diagnostic>

Signature links:from_jsonu8FieldDecoderLimitsResultDiscreteFieldEnvelopeV1Diagnostic

Decode with byte, nesting, entity, component, and scalar-value limits.

This operation performs no filesystem, network, or mesh lookup.

§Errors

Returns EQ0901 for malformed/unknown wire data, resource excess, invalid digest/count/shape/value data, or a non-canonical negative zero.

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 SHA-256 identity of the complete mesh-bound field.

§Errors

Returns EQ0901 if canonical serialization fails.

pub fn mesh_artifact(&self) -> ArtifactDigest

Signature links:mesh_artifactArtifactDigest

Exact affine-simplex mesh content identity named by this envelope.

pub const fn association(&self) -> DiscreteFieldAssociation

Signature links:associationDiscreteFieldAssociation

Mesh entity stratum carrying the values.

pub const fn component_shape(&self) -> DiscreteFieldShape

Signature links:component_shapeDiscreteFieldShape

Component shape retained in field identity.

pub fn entity_count(&self) -> Result<usize, Diagnostic>

Signature links:entity_countResultusizeDiagnostic

Portable entity count after checked conversion to local usize.

§Errors

Returns EQ0901 when the stored u64 is not representable locally.

pub fn values(&self) -> &[f64]

Signature links:valuesf64

Canonical entity-major scalar values.

These values remain bound to Self::mesh_artifact, Self::association, and Self::component_shape. The projection is provided so higher-level typed artifacts can validate spatial support without inventing a second array representation.

pub fn validate_mesh_artifact( &self, mesh: &SimplicialMeshEnvelopeV1, ) -> Result<DiscreteFieldPayload, Diagnostic>

Signature links:validate_mesh_artifactSimplicialMeshEnvelopeV1ResultDiscreteFieldPayloadDiagnostic

Validate exact mesh linkage and reconstruct the accepted L2 payload.

Equal entity counts are insufficient: the supplied mesh envelope must have the exact content digest named by this field.

§Errors

Returns EQ0901 for a different mesh identity, association/count mismatch, or any payload invariant failure.
