Module lattices::test

Helper test utils to test lattice implementation correctness.

Functions

• cartesian_power
  Returns an iterator of N-length arrays containing all permutations of items (with replacement).
• check_all
  Helper which calls many other check_* functions in this module. See source code for which functions are called.
• check_atomize_each
  Check that the atomized lattice points re-merge to form the same original lattice point, for each item in items.
• check_lattice_bimorphism
  Checks that the LatticeBimorphism is valid, i.e. that merge distributes over both arguments of it.
• check_lattice_default_is_bot
  Asserts that IsBot is true for Default::default().
• check_lattice_is_bot
  Checks that the item which is bot is less than (or equal to) all other items.
• check_lattice_is_top
  Checks that the item which is top is greater than (or equal to) all other items.
• check_lattice_morphism
  Checks that the LatticeMorphism is valid, i.e. that merge distributes over it.
• check_lattice_ord
  Check that the lattice’s PartialOrd implementation agrees with the NaiveLatticeOrd partial order derived from Merge.
• check_lattice_properties
  Check lattice associativity, commutativity, and idempotence.
• check_partial_ord_properties
  Checks PartialOrd and PartialEq’s reflexivity, symmetry, transitivity, and duality.
