Struct ExplanationBlock 

pub struct ExplanationBlock {
    pub producer_node: NodeId,
    pub method: String,
    pub target_name: Option<String>,
    pub payload: Value,
}

An EXPLAIN-phase output block (ADR-12 explain contract). Explanations are a node output returned in the NodeResult — like predictions, they cross as data, not as an opaque host handle. The payload shape is controller-defined (e.g. per-feature importances); the core does not interpret it. Explanations are only valid in the EXPLAIN phase.

Fields

producer_node: NodeId

Node whose model the explanation describes (must equal the producing node).

method: String

Stable explanation method identifier, e.g. shap, permutation_importance.

target_name: Option<String>

Optional target/output name the explanation pertains to.

payload: Value

Controller-defined explanation payload as canonical JSON.

Implementations

impl ExplanationBlock

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

Validate the intrinsic shape of the explanation block (method/target_name non-empty). Producer identity is checked against the node in NodeResult::validate_for_task.

Trait Implementations

impl Clone for ExplanationBlock

fn clone(&self) -> ExplanationBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExplanationBlock

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExplanationBlock

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ExplanationBlock

fn eq(&self, other: &ExplanationBlock) -> 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 ExplanationBlock

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.
