Enum OperationResult 

pub enum OperationResult {
    Value(BoundValueKind),
    Veto(VetoType),
}

Result of evaluating a rule, expression, or data leaf.

Variants

Value(BoundValueKind)

Operation produced a value (canonical magnitude + optional written unit)

Veto(VetoType)

Operation was vetoed (valid result, no value)

Implementations

impl OperationResult

pub fn from_literal(value: LiteralValue) -> Self

Wrap a typeless literal with no written-unit binding.

pub fn from_bound(bound: BoundValueKind) -> Self

pub fn vetoed(&self) -> bool

pub fn is_missing_data(&self) -> bool

True when this result is a VetoType::MissingData or VetoType::MissingRowData veto.

pub fn value(&self) -> Option<&BoundValueKind>

pub fn literal_value(&self) -> Option<LiteralValue>

Typeless payload (written unit dropped). Prefer Self::value when the binding matters.

pub fn number(number: Decimal) -> Self

pub fn measure( value: Decimal, unit: impl Into<String>, lemma_type: Option<LemmaType>, ) -> Self

pub fn text(text: impl Into<String>) -> Self

pub fn date(date: impl Into<SemanticDateTime>) -> Self

pub fn time(time: impl Into<SemanticTime>) -> Self

pub fn boolean(boolean: bool) -> Self

pub fn ratio(rational: Decimal) -> Self

pub fn veto(veto: impl Into<String>) -> Self
