Module `Hint.Morph`

type 'd t constraint 'd = 'l * 'r

Hints that explain morphisms. The allowance 'd describes if the morphism can be on the LHS or RHS of submode.

val id : 'd t

The hint for the identity morphism

val left_adjoint : 
  Pinpoint.t ->
  (_ * Allowance.allowed) t ->
  Pinpoint.t * (Allowance.allowed * Allowance.disallowed) t

Given a hint for a mode morphism with its destination pinpoint, return a hint for the left adjoint of the morphism with the opposite pinpoint.

val right_adjoint : 
  Pinpoint.t ->
  (Allowance.allowed * _) t ->
  Pinpoint.t * (Allowance.disallowed * Allowance.allowed) t

Given a hint for a mode morphism with its destination pinpoint, return a hint for the right adjoint of the morphism with the opposite pinpoint.

val unknown : 'd t

The hint for unexplained morphs

include Allowance.Allow_disallow with type (_, _, 'd) sided = 'd t

type (_, _, 'd) sided = 'd t

val disallow_right : 
  ('a, 'b, 'l * 'r) sided ->
  ('a, 'b, 'l * Allowance.disallowed) sided

Disallows on the right.

val disallow_left : 
  ('a, 'b, 'l * 'r) sided ->
  ('a, 'b, Allowance.disallowed * 'r) sided

Disallows a the left.

val allow_right : 
  ('a, 'b, 'l * Allowance.allowed) sided ->
  ('a, 'b, 'l * 'r) sided

Generalizes a right-hand-side allowed to be any allowance.

val allow_left : 
  ('a, 'b, Allowance.allowed * 'r) sided ->
  ('a, 'b, 'l * 'r) sided

Generalizes a left-hand-side allowed to be any allowance.
