Module Types.Separability

see Typedecl_separability for an explanation of separability and separability modes.

type t =
  1. | Ind
  2. | Sep
  3. | Deepsep
val eq : t -> t -> bool
val print : Format.formatter -> t -> unit
val rank : t -> int

Modes are ordered from the least to the most demanding: Ind < Sep < Deepsep. 'rank' maps them to integers in an order-respecting way: m1 < m2 <=> rank m1 < rank m2

val compare : t -> t -> int

Compare two mode according to their mode ordering.

val max : t -> t -> t

max_mode m1 m2 returns the most demanding mode. It is used to express the conjunction of two parameter mode constraints.

type signature = t list

The 'separability signature' of a type assigns a mode for each of its parameters. ('a, 'b) t has mode (m1, m2) if (t1, t2) t is separable whenever t1, t2 have mode m1, m2.

val print_signature : Format.formatter -> signature -> unit
val default_signature : arity:int -> signature

The most pessimistic separability for a completely unknown type.
