Function split_conjunction

datafusion/physical-expr/src/utils/mod.rs:43–47

Assume the predicate is in the form of CNF, split the predicate to a Vec of PhysicalExprs. For example, split "a1 = a2 AND b1 <= b2 AND c1 != c2" into ["a1 = a2", "b1 <= b2", "c1 != c2"]

(
    predicate: &Arc<dyn PhysicalExpr>,
)

///
/// For example, split "a1 = a2 AND b1 <= b2 AND c1 != c2" into ["a1 = a2", "b1 <= b2", "c1 != c2"]
pub fn split_conjunction(
    predicate: &Arc<dyn PhysicalExpr>,
) -> Vec<&Arc<dyn PhysicalExpr>> {
    split_impl(Operator::And, predicate, vec![])
}

impl ConstExpr {
    /// Collects predicate-derived constants from equality conjunctions.
