Struct PolicySpec 

pub struct PolicySpec {
    pub version: u32,
    pub description: Option<String>,
    pub classifications: Vec<Classification>,
    pub rules: Vec<PolicyRule>,
}

Available on crate feature policy only.

A data-flow policy: classifications (which columns carry which label) and rules (what a labelled column requires of the sink it lands in). Declared once — in a policy file passed with --policy, in a deployment overlay, or as a top-level policy: block — and evaluated against every pipeline before any data moves; a value detector re-checks at run time.

Fields

version: u32

Policy grammar version. Only 1 exists.

description: Option<String>

Free-form description shown by faucet policy.

classifications: Vec<Classification>

How columns get their labels.

rules: Vec<PolicyRule>

What each label demands of a destination.

Implementations

impl PolicySpec

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

Fail-fast validation, surfaced at config load. A policy that does not validate is refused outright — a broken policy must fail closed.

pub fn merge(self, other: PolicySpec) -> Result<PolicySpec, String>

Merge another policy in (classifications and rules appended). A rule name present on both sides is an error — two sources must not silently override each other.

pub fn has_value_detectors(&self) -> bool

Whether any classification uses a value detector (so the runtime backstop has something to do).

Trait Implementations

impl Clone for PolicySpec

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 PolicySpec

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

Formats the value using the given formatter.

impl Default for PolicySpec

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PolicySpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PolicySpec

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 PartialEq for PolicySpec

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for PolicySpec

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
