Struct pergola::ArcOrdMapWithUnion

pub struct ArcOrdMapWithUnion<K: DefTraits, VD: LatticeDef> { /* fields omitted */ }

This is a lattice for maps that contain other lattices as values. The join operator takes the union of (key, value) pairs for keys present in only one map -- equivalent to an elementwise join-with-unit -- and the elementwise join of values for keys that exist in both maps.

As with BitSet, this avoids the typical lexicographic order on maps in favour of the join-induced partial order: a subset relation extended with the lattice orders of the values when the same key is present in both maps.
