Struct SlaSpec 

pub struct SlaSpec {
    pub max_staleness_secs: Option<u64>,
    pub min_rows_per_run: Option<u64>,
    pub volume_anomaly: Option<VolumeAnomalySpec>,
}

Declared service-level agreement for a pipeline: freshness and volume expectations. Violations emit the faucet_pipeline_sla_violations_total{pipeline,row,kind} counter and a structured warning log; they never fail the run.

Fields

max_staleness_secs: Option<u64>

Maximum seconds since the last successful run before the pipeline counts as stale. Evaluated when a run fails (against the previous success) and by faucet doctor. Requires a state: block to persist the last-success timestamp.

min_rows_per_run: Option<u64>

Static volume floor: a successful run that writes fewer records than this violates the SLA (catches a source silently returning nothing). Stateless — works without a state: block.

volume_anomaly: Option<VolumeAnomalySpec>

Learned-baseline volume anomaly detection over recent successful runs. Requires a state: block to persist the rolling baseline.

Implementations

impl SlaSpec

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

Fail-fast validation, surfaced at config-load time by expand.

pub fn needs_state(&self) -> bool

Whether any configured check needs persisted history (a state: block).

pub fn window(&self) -> usize

The rolling-window size to keep in the persisted baseline. Volumes are tracked even when volume_anomaly is unset (as long as a state store exists) so enabling anomaly detection later starts with warm history.

Trait Implementations

impl Clone for SlaSpec

fn clone(&self) -> SlaSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SlaSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SlaSpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for SlaSpec

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 SlaSpec

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
