Struct QualityPolicy 

pub struct QualityPolicy { /* private fields */ }

What a report must satisfy.

Build one with the chainable setters, then evaluate it against a report. Requirements are evaluated in a fixed order that does not depend on the order they were added, so two callers stating the same policy get the same document out.

Implementations

impl QualityPolicy

pub fn new() -> Self

An empty policy. It states no requirement, so evaluating it as-is is a PolicyError::NoRequirements.

pub fn min_quality_score(self, min: f64) -> Self

Require the overall quality score to be at least min (0..=100).

pub fn min_dimension_score(self, dimension: QualityDimension, min: f64) -> Self

Require one dimension’s score to be at least min (0..=100).

pub fn max_null_percentage(self, column: impl Into<String>, max: f64) -> Self

Require the named column’s null percentage to be at most max (0..=100). Takes precedence over max_null_percentage_any for that column.

pub fn max_null_percentage_any(self, max: f64) -> Self

Require every other profiled column’s null percentage to be at most max (0..=100).

pub fn max_duplicate_rows(self, max: usize) -> Self

Require the report to count at most max duplicate rows.

pub fn require_quality(self) -> Self

Require the report to carry a quality assessment at all.

Without this, a report with no assessment leaves quality requirements unevaluated and the verdict inconclusive. With it, the absence is itself a violation — which is what a pipeline wants when quality is supposed to be configured on.

pub fn require_dimension(self, dimension: QualityDimension) -> Self

Require a specific dimension to have been assessed.

pub fn scope(self, scope: PolicyScope) -> Self

Set what the requirements are statements about. Defaults to PolicyScope::FullSource.

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

Check that the policy is evaluable, without needing a report.

Callers that read a policy out of configuration should do this at startup rather than discovering a bad threshold on the first dataset.

pub fn evaluate( &self, report: &ProfileReport, ) -> Result<GateResult, PolicyError>

Evaluate the policy against a report.

Returns the structured outcome. The report is not modified, nothing is printed, and the process is not exited: what to do about a failing gate is the caller’s decision.
