Env (preface.Preface

Using the minimal definition

Build an Preface_specs.ENV over an Inner Preface_specs.COMONAD.

module Over_comonad
  (C : Preface_specs.COMONAD)
  (Env : Preface_specs.Types.T0) : 
  Preface_specs.ENV with type env = Env.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.ENV API with these complementary implementations

Functor

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

module Functor
  (F : Preface_specs.FUNCTOR)
  (Env : Preface_specs.Types.T0) : 
  Preface_specs.FUNCTOR with type 'a t = Env.t * 'a F.t

Applicative

If the Inner Preface_specs.COMONAD is also an Preface_specs.APPLICATIVE and the Env is a Preface_specs.MONOID , the Env comonad is also a Preface_specs.APPLICATIVE.

module Applicative
  (A : Preface_specs.APPLICATIVE)
  (Env : Preface_specs.MONOID) : 
  Preface_specs.APPLICATIVE with type 'a t = Env.t * 'a A.t

Comonad

If the Inner Preface_specs.COMONAD is also a Preface_specs.COMONAD, the Env 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)
  (Env : Preface_specs.Types.T0) : 
  Preface_specs.COMONAD with type 'a t = Env.t * 'a C.t

Manual construction

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

Building Core

module Core_over_comonad
  (C : Preface_specs.COMONAD)
  (Env : Preface_specs.Types.T0) : 
  Preface_specs.Env.CORE with type env = Env.t and type 'a comonad = 'a C.t
