Module `Univ.ContextSet`

type t = Level.Set.t constrained

val empty : t

val of_instance : Instance.t -> t
val of_set : Level.Set.t -> t
val equal : t -> t -> bool
val union : t -> t -> t
val append : t -> t -> t: Variant of union which is more efficient when the left argument is much smaller than the right one.

val add_universe : Level.t -> t -> t
val add_constraints : Constraints.t -> t -> t
val add_instance : Instance.t -> t -> t
val sort_levels : Level.t array -> Level.t array: Arbitrary choice of linear order of the variables

val to_context : (Instance.t -> Names.Name.t array) -> t -> UContext.t: Build a vector of universe levels assuming a function generating names

val of_context : UContext.t -> t
val constraints : t -> Constraints.t
val levels : t -> Level.Set.t
val size : t -> int: The number of universes in the context
