Fields

kind: ObservationKind

column: String

affected_rows: usize

evaluated_rows: usize

fact: String

What only the engine can say of a drift or audio measurement: the files, the runs. Empty for every kind the report phrases from the numbers itself.

normalized_category: Option<String>

files: Vec<QualityFileEvidence>

The files behind an ObservationKind::Absent or ObservationKind::TypeConflict measurement, commonest first; empty for checks over values.

time_format: Option<TimeInterpretation>

The format an ObservationKind::UnparsedTime measurement read the text with.

full_scale: Option<(f64, f64)>

The values at or past which an audio sample is at full scale, for an ObservationKind::Clipping measurement’s rows.

Implementations

impl QualityObservation

pub fn evidence_scope(&self) -> Option<QualityScope>

The scope holding this observation’s rows when they are a set of files (absent or conflicting cells have no value to filter on).

pub fn evidence_predicate(&self, results: &DataQualityResults) -> Option<Expr>

The rows behind this observation as a predicate over the run’s rows; the engine counts with the same expression where it can, so count and rows agree.

Trait Implementations

impl Clone for QualityObservation

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QualityObservation

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

Formats the value using the given formatter.
