Module `UnivMinim`Source

Sourcemodule UPairSet : CSet.S with type elt = Univ.Level.t * Univ.Level.t

Unordered pairs of universe levels (ie (u,v) = (v,u))

Sourcetype extra = {

weak_constraints : UPairSet.t;
above_prop : Univ.Level.Set.t;

Simplification and pruning of constraints: normalize_context_set ctx us

Instantiate the variables in us with their most precise universe levels respecting the constraints.

Normalizes the context ctx w.r.t. equality constraints, choosing a canonical universe in each equivalence class (a global one if there is one) and transitively saturate the constraints w.r.t to the equalities.
