Fields

prediction_id: Option<String>

producer_node: NodeId

variant_id: Option<VariantId>

Variant this score belongs to — distinguishes per-variant candidates when a generated campaign scores several variants, so native SELECT can pick the best. Skipped (None) for single-variant runs, so existing fixtures/fingerprints are byte-identical.

variant_label: Option<String>

Cross-language CONTENT fingerprint (hex sha256) of the operator-variant this score belongs to: the canonical form of the variant’s LOWERED operator sub-sequence (Phase 5). The nirs4all host recomputes the SAME bytes from its own operator-choice config, so it can map a per-variant dag-ml report back to the config that produced it (replacing a brittle positional zip). Set only for operator-SELECT reports (the choice fingerprint from OperatorVariantModel’s variant_labels); skipped (None) for param-variant / single-variant runs, so existing fixtures/fingerprints stay byte-identical.

partition: PredictionPartition

Implementations

impl RegressionMetricReport

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

pub fn into_candidate_score( self, candidate_id: impl Into<String>, ) -> Result<CandidateScore, DagMlError>

Trait Implementations

impl Clone for RegressionMetricReport

fn clone(&self) -> RegressionMetricReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegressionMetricReport

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RegressionMetricReport

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RegressionMetricReport

fn eq(&self, other: &RegressionMetricReport) -> 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 RegressionMetricReport

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.
