Struct DatasetViewEnvelopeV1 

pub struct DatasetViewEnvelopeV1 { /* private fields */ }
Description

Reference-only selection over an immutable spatial trajectory.

V1 deliberately supports only identity transformation, no normalization, and one unpartitioned split. It copies no numerical values; richer Dataset materialization and ML semantics remain separate later contracts.

Implementations§

§

impl DatasetViewEnvelopeV1

Signature links:§DatasetViewEnvelopeV1

pub fn identity_window( context: &ValidatedFixedSpatialContextV1<'_>, trajectory: &SpatialTrajectoryEnvelopeV1, segments: &[SpatialTrajectorySegmentEnvelopeV1], first_step: u64, last_step: u64, fields: impl IntoIterator<Item = Id<Field>>, ) -> Result<DatasetViewEnvelopeV1, Diagnostic>

Signature links:identity_windowValidatedFixedSpatialContextV1SpatialTrajectoryEnvelopeV1SpatialTrajectorySegmentEnvelopeV1u64u64IntoIteratorIdFieldResultDatasetViewEnvelopeV1Diagnostic

Select an inclusive accepted-step window and exact Field subset.

Input Field order is normalized by identity.

§Errors

Returns EQ0901 for an empty/duplicate/foreign Field selection or a window outside the source trajectory.

pub fn from_json( bytes: &[u8], limits: TrajectoryDecoderLimits, ) -> Result<DatasetViewEnvelopeV1, Diagnostic>

Signature links:from_jsonu8TrajectoryDecoderLimitsResultDatasetViewEnvelopeV1Diagnostic

Decode without loading the source trajectory or any numerical values.

§Errors

Returns EQ0901 for malformed, oversized, unknown, or noncanonical data.

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

Signature links:canonical_jsonResultVecu8Diagnostic

Deterministic canonical JSON bytes containing no numerical values.

§Errors

Returns EQ0901 if serialization unexpectedly fails.

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

Signature links:digestResultArtifactDigestDiagnostic

Domain-separated derived-view identity.

§Errors

Returns EQ0901 if canonical serialization fails.

pub fn trajectory(&self) -> ArtifactDigest

Signature links:trajectoryArtifactDigest

Exact immutable source trajectory root.

pub const fn step_window(&self) -> (u64, u64)

Signature links:step_windowu64u64

Inclusive accepted-step window.

pub fn fields(&self) -> Vec<Id<Field>>

Signature links:fieldsVecIdField

Canonically ordered exact Field selection.

pub fn states(&self) -> Vec<(u64, f64, ArtifactDigest)>

Signature links:statesVecu64f64ArtifactDigest

Exact selected accepted-state references, with no copied Field values.

pub fn validate_against( &self, context: &ValidatedFixedSpatialContextV1<'_>, trajectory: &SpatialTrajectoryEnvelopeV1, segments: &[SpatialTrajectorySegmentEnvelopeV1], ) -> Result<(), Diagnostic>

Signature links:validate_againstValidatedFixedSpatialContextV1SpatialTrajectoryEnvelopeV1SpatialTrajectorySegmentEnvelopeV1Result()Diagnostic

Rebuild and compare the selection against its exact source trajectory.

§Errors

Returns EQ0901 for source substitution or selection drift.
