pub type InferredSchemas = BTreeMap<String, Vec<Option<ScalarType>>>;Expand description
Per-predicate inferred schema. Vec length equals the head
arity; each element is Some(t) if inference established the
column’s type, or None if the column remains unknowable
(e.g., cyclic-only predicate, or a head term whose body atoms
don’t type the corresponding variable).
