Fields

total_rows: Option<usize>

evaluated_rows: usize

precision: QualityPrecision

sample_seed: u64

columns: Vec<ColumnQualityProfile>

observations: Vec<QualityObservation>

segments: Vec<SegmentQualityProfile>

temporal: Vec<TemporalLatencyProfile>

identity: Option<IdentityProfile>

category_variants: Vec<CategoryVariantGroup>

shared_nulls: Vec<SharedNulls>

source_files: Option<usize>

How many source files’ footers were compared, when the scope has files to compare. None means the checks that compare files could not run.

per_value: Option<usize>

Rows an equal-per-value sample kept of each value. See crate::sampling::PerValue.

footers_read: Option<usize>

How many of source_files had their footers read: fewer on a dataset too large to read every footer, where the file checks cover only those.

reads: Option<ObservedReads>

What the run’s reads of the source were seen to do. None for results no watched run produced.

examples: Vec<FindingExamples>

Values behind text findings, from the rows the run kept; empty after a full scan.

unsampled_segments: Vec<UnsampledSegment>

Segments a sampled run counted rows in but drew none of, in segment order: the rows are there, the sample did not reach them. Not in segments, which profile only what was read.

intent: Option<Box<IntentResults>>

What the declared column intent found; None when nothing was declared.

source: Option<Box<SourceIdentity>>

What the rows were read from, as the run that measured them labeled it.

Implementations

impl DataQualityResults

pub fn estimated_bytes(&self) -> usize

Memory the report holds, near enough to budget by: a profile per column, and another per column of every segment, which is what grows, and the text it keeps, whole in spellings and cut short in examples.

pub fn compare_segments(&mut self, plan: &DataQualityPlan)

pub fn empty( total_rows: Option<usize>, plan: &DataQualityPlan, schema: &Schema, ) -> Self

pub fn examples_of(&self, kind: ObservationKind, column: &str) -> &[String]

The kept examples of kind in column.

Trait Implementations

impl Clone for DataQualityResults

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 DataQualityResults

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

Formats the value using the given formatter.
