Struct CausalEdgeData 

pub struct CausalEdgeData {
    pub strength: f32,
    pub confidence: f32,
    pub evidence_count: u32,
    pub confounders: Vec<String>,
    pub provenance: Option<String>,
    pub mechanism: Option<String>,
    pub direction: Option<CausalDirection>,
}

Data carried only on causal edges — boxed to keep GraphEdge small for the common non-causal case.

Required numeric fields use concrete values rather than Option because a CausalEdgeData that exists but has no strength/confidence/count is not meaningful. Defaults are: strength = 0.0, confidence = 0.5, evidence_count = 0, confounders = [].

Fields

strength: f32

Causal effect magnitude [0.0, 1.0].

confidence: f32

Certainty in the causal claim [0.0, 1.0].

evidence_count: u32

Number of observations supporting this edge.

confounders: Vec<String>

Known confounding variables.

provenance: Option<String>

Provenance description (free text or JSON reference).

mechanism: Option<String>

Described causal mechanism.

direction: Option<CausalDirection>

Causal direction label.

Implementations

impl CausalEdgeData

pub fn new(strength: f32, confidence: f32, evidence_count: u32) -> Self

Construct with the three required numeric fields; all optional fields are initialised to their defaults.

pub fn with_mechanism(self, mechanism: impl Into<String>) -> Self

Builder: set the causal mechanism description.

pub fn with_provenance(self, provenance: impl Into<String>) -> Self

Builder: set the provenance reference.

pub fn with_direction(self, direction: CausalDirection) -> Self

Builder: set the causal direction label.

pub fn with_confounders(self, confounders: Vec<String>) -> Self

Builder: set known confounding variables.
