pomaps

Maps and sets of partial orders.

Maps (and sets) indexed by keys satisfying PartialOrd.

The goal is to provide asymptotically better data structures than simple association lists or lookup tables. Asymptotics depend on the partial order used as keys, its width w specifically (the size of the biggest anti-chain).

For partial orders of great width, this package won't provide any benefit over using association lists, so benchmark for your use-case!
