Type

type ('a, 'b) t = ('a, 'b) F.t * ('a, 'b) G.t

The type held by the Category.

Functions

include Preface_specs.Category.WITH_ID with type ('a, 'b) t := ('a, 'b) t
val id : ('a, 'a) t

The identity morphism.

include Preface_specs.Semigroupoid.WITH_COMPOSE with type ('a, 'b) t := ('a, 'b) t
val compose : ('b, 'c) t -> ('a, 'b) t -> ('a, 'c) t

Morphism composition (from right to left).

val compose_right_to_left : ('b, 'c) t -> ('a, 'b) t -> ('a, 'c) t

An alias of CORE.compose.

val compose_left_to_right : ('a, 'b) t -> ('b, 'c) t -> ('a, 'c) t

An alias of CORE.compose with flipped argument.

Infix operators

module Infix : Preface_specs.Category.INFIX with type ('a, 'b) t = ('a, 'b) t
val (%) : ('b, 'c) t -> ('a, 'b) t -> ('a, 'c) t

An alias of CORE.compose (to be iso with Preface_core).

val (<%) : ('b, 'c) t -> ('a, 'b) t -> ('a, 'c) t

An alias of CORE.compose (to be iso with Preface_core).

val (%>) : ('a, 'b) t -> ('b, 'c) t -> ('a, 'c) t

An alias of OPERATION.compose_left_to_right (to be iso with Preface_core).

val (<<<) : ('b, 'c) t -> ('a, 'b) t -> ('a, 'c) t

An alias of CORE.compose (to be iso with Haskell's approach). Even <<< looks like <% (it is an alias for the same function), they differ in their priorities. OCaml documentation of operators priorities

val (>>>) : ('a, 'b) t -> ('b, 'c) t -> ('a, 'c) t

An alias of CORE.compose_left_to_right (to be iso with Haskell's approach). Even >>> looks like %> (it is an alias for the same function), they differ in their priorities. OCaml documentation of operators priorities
