Module Core_kernel.Debug.Make

Debug.Make produces a debug function used to wrap a function to display arguments before calling and display results after returning. Intended usage is:

      module Foo = struct
        type t = ...
        let invariant = ...
          let bar t x y : Result.t = ...
      end
      module Foo_debug = struct
        open Foo
        include Debug.Make ()
        let debug x = debug invariant ~module_name:"Foo" x
        let bar t x y =
          debug "bar" [t] (t, x, y) <:sexp_of< t * X.t * Y.t >> <:sexp_of< Result.t >>
            (fun () -> bar t x y)
      end
