Available on crate feature quality only.

A per-batch check, evaluated per page over the survivors of the per-record pass.

Variants

RowCount

Survivor count is within [min, max] (at least one bound required).

Fields

min: Option<usize>

max: Option<usize>

on_failure: OnFailure

NullRate

Null-or-missing rate of field across survivors is <= max.

Fields

field: String

max: f64

Maximum allowed null-or-missing proportion, in [0.0, 1.0]. Out-of-range values are rejected at compile time.

on_failure: OnFailure

Unique

The composite fields tuple is unique across survivors.

Fields

fields: Vec<String>

on_failure: OnFailure

DistinctCount

Distinct values of field across survivors is within [min, max].

Fields

field: String

min: Option<usize>

max: Option<usize>

on_failure: OnFailure

Trait Implementations

impl Clone for BatchCheck

fn clone(&self) -> BatchCheck

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BatchCheck

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BatchCheck

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for BatchCheck

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for BatchCheck

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
