Struct ChainProvenance 

pub struct ChainProvenance {
    pub producer_kind: String,
    pub producer_value: String,
}

Provenance for Phase 2 chain-derived ProbeSpecs.

Attached by generate_dag_chained_plan so downstream consumers can trace the harvested signal that produced this probe — e.g. an If-Match probe whose value was harvested from an ETag response header carries producer_kind = "Etag" and producer_value = "W/\"abc\"".

Fields

producer_kind: String

Discriminant from ProducerOutputKind as a stable string, e.g. "Etag".

producer_value: String

Serialized representation of the harvested value, e.g. "W/\"abc123\"".

Trait Implementations

impl Clone for ChainProvenance

fn clone(&self) -> ChainProvenance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainProvenance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChainProvenance

fn deserialize<__D>( __deserializer: __D, ) -> Result<ChainProvenance, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChainProvenance

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ChainProvenance

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ChainProvenance
