Available on crate feature quality only.

A per-record check. Addressed field accepts the filter/explode path subset (bare key, dot.path, $['bracketed']).

Every variant carries field (the path to check) and on_failure (what a failure does). Per-record checks accept only OnFailure::Quarantine or OnFailure::Abort — quarantine_batch is rejected at compile time because a per-record failure is always attributable to one row.

Variants

NotNull

Field present and non-null.

Fields

field: String

Path to the checked field.

treat_missing_as_null: bool

When true (default) a missing field fails; when false only an explicit JSON null fails.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

NotEmpty

Field is a string, non-empty after trim().

Fields

field: String

Path to the checked field. A missing field, a null, or a non-string value all fail.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

RegexMatch

Field is a string matching pattern.

Fields

field: String

Path to the checked field. A missing field or a non-string value fails.

pattern: String

Rust regex-crate pattern. Unanchored — it only has to match somewhere in the value, so anchor with ^…$ for a full match. An invalid pattern is rejected at config load, never mid-run.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

ValueInSet

Field value is a member of values (exact JSON equality).

Fields

field: String

Path to the checked field. A missing field fails.

values: Vec<Value>

The allowed values. Must be non-empty. Compared by JSON equality with no type coercion, so the string "5" does not match the number 5.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

NotInSet

Field value is NOT a member of values (exact JSON equality).

Fields

field: String

Path to the checked field. A missing field passes — there is no value to forbid.

values: Vec<Value>

The forbidden values. Must be non-empty. Compared by JSON equality with no type coercion.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

Compare

Field value compares against value under op.

Fields

field: String

Path to the checked field. A missing field fails.

op: CompareOp

The comparison to apply, as field <op> value.

value: Value

The right-hand side of the comparison. The ordering ops (gt/gte/lt/lte) require a JSON number here — anything else is rejected at config load — and also require the record’s value to be a number; eq/ne accept any JSON value.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

TypeIs

Field’s JSON type equals expected.

Fields

field: String

Path to the checked field. A missing field fails, which is distinct from an expected: null match on a present null.

expected: JsonType

The required JSON type.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

StringLength

Field is a string whose char count is within [min, max].

Fields

field: String

Path to the checked field. A missing field or a non-string value fails.

min: Option<usize>

Inclusive minimum length in Unicode characters (not bytes). Omit for no lower bound.

max: Option<usize>

Inclusive maximum length in Unicode characters (not bytes). Omit for no upper bound. At least one of min/max is required, and min <= max, both enforced at config load.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

JsonSchema

Available on crate feature quality-jsonschema only.

The whole record validates against a JSON Schema document.

Fields

schema: Value

The JSON Schema document, inline. Compiled once at config load — an invalid schema fails there, not on the first page. The first validation error becomes the DLQ/abort message.

on_failure: OnFailure

What a failure does: quarantine (row to the DLQ) or abort.

Trait Implementations

impl Clone for RecordCheck

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 RecordCheck

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RecordCheck

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for RecordCheck

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 RecordCheck

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
