Variants

RuleRef

Reference to a rule in the enclosing explanation’s rules table.

Fields

id: ExplainedRuleId

name: RulePath

result: RuleResultValue

Compose

Fields

expression: String

operator: Option<ArithmeticComputation>

operands: Vec<ExplanationNode>

Data

Evaluated / bound data narration. Result fields flatten like crate::evaluation::response::RuleResult.

Fields

name: DataPath

result: RuleResultValue

DataUnused

Structural mention of a data path that was not looked up for this cause (short-circuit skip or static record narration without a binding).

Fields

name: DataPath

Conversion

Fields

expression: String

steps: Vec<SerializedConversionTraceStep>

operands: Vec<ExplanationNode>

Veto

Fields

message: Option<String>

Row

One instance-list row the enclosing command read.

Fields

number: usize

appended: bool

key: Vec<ExplanationNode>

fields: Vec<ExplanationNode>

Filter

Summary of a where filter: how many of the input rows matched.

Fields

condition: String

matched: usize

total: usize

children: Vec<ExplanationNode>
