Struct EvaluatedSource 

Source 
pub struct EvaluatedSource {
    pub values: Vec<Value>,
    pub cardinality: u64,
    pub index_fn: IndexFn,
}
Expand description

Result of evaluating one clause’s source.

values carries the materialized stream (one Value per output position). cardinality is the count of values (values.len() as u64, equivalent to the IndexFn’s axis total for discrete sources; 0 for un-sampled continuous sources). index_fn is the addressing scheme the emitted values actually satisfy — derived from observed shape for Generator / WorkloadParamList, declared for static variants.

Fields§

§values: Vec<Value>

The values, in dispense order.

§cardinality: u64

How many values; zero for an unsampled continuous source.

§index_fn: IndexFn

The addressing scheme the values satisfy.
