Function differential_dataflow::lattice::antichain_meet

pub fn antichain_meet<T: Lattice + Clone>(
    one: &[T],
    other: &[T],
) -> Antichain<T>

Returns the “greatest” minimal antichain “less or equal” to both inputs.

This method is primarily meant for cases where one cannot use the methods of Antichain’s PartialOrder implementation, such as when one has only references rather than owned antichains.

Examples

let f1 = &[Product::new(3, 7), Product::new(5, 6)];
let f2 = &[Product::new(4, 6)];
let meet = antichain_meet(f1, f2);
assert_eq!(&*meet.elements(), &[Product::new(3, 7), Product::new(4, 6)]);
