Module `Preface_make.Traced`

Building a Preface_specs.Traced, a Traced transformer.

Using the minimal definition

Build an Preface_specs.TRACED over an Inner Preface_specs.COMONAD.

module Over_comonad
  (C : Preface_specs.COMONAD)
  (Tape : Preface_specs.MONOID) : 
  Preface_specs.TRACED with type tape = Tape.t and type 'a comonad = 'a C.t

Improving API

If there are complementary implementations to Preface_specs.COMONAD attached to the Inner Preface_specs.COMONAD type, it is possible to promote the Preface_specs.TRACED API with these complementary implementations

Functor

If the Inner Preface_specs.COMONAD is also a Preface_specs.FUNCTOR, the Traced comonad is also a Preface_specs.FUNCTOR.

module Functor
  (F : Preface_specs.FUNCTOR)
  (Tape : Preface_specs.MONOID) : 
  Preface_specs.FUNCTOR with type 'a t = (Tape.t -> 'a) F.t

Comonad

If the Inner Preface_specs.COMONAD is also a Preface_specs.COMONAD, the Traced comonad is also a Preface_specs.COMONAD (this is this functor which is used in the full API definition).

module Comonad
  (C : Preface_specs.COMONAD)
  (Tape : Preface_specs.MONOID) : 
  Preface_specs.COMONAD with type 'a t = (Tape.t -> 'a) C.t

Manual construction

Advanced way to build an Preface_specs.TRACED, constructing and assembling a component-by-component of Preface_specs.TRACED. (In order to provide your own implementation for some features.)

Building Core

module Core_over_comonad
  (C : Preface_specs.COMONAD)
  (Tape : Preface_specs.MONOID) : 
  Preface_specs.Traced.CORE
    with type tape = Tape.t
     and type 'a comonad = 'a C.t
