Utility relations.
This module defines convenient signatures for the useful equality and total ordering relations on a monomorphic type.
module type Order = sig ... endModule type defining a type t and a corresponding total ordering function, of the sort generated by Ppx_deriving, which returns the same value as the standard Stdlib.compare function.
Use min (module M: Order) a b to select the minimum of a and b according to the total order M.
Use max (module M: Order) a b to select the maximum of a and b according to the total order M.
module type Equal = sig ... endModule type defining a type t and a corresponding equality relation function, of the sort generated by Ppx_deriving, which returns the same value as the standard Stdlib.(=) operator.
module type Std = sig ... endModule type definining a type t and the corresponding equality and total ordering relation functions, of the sort generated by Ppx_deriving, which return the same value as the standard Stdlib.(=) and Stdlib.compare functions
The equality and total ordering relation for standard integers. Prefer the Stdlib.Int module, if available.
module Extensible : sig ... endA submodule to facilitate relations on extensible types.
