Timed references for imperative state

This minimal library allows the encapsulation of reference updates in an abstract notion of state. It can be used to emulate a pure interface while working with references.

Authors: Rodolphe Lepigre & Christophe Raffalli

Installation

The library has no dependency, but it is built using dune. You can use the following commands to compile and install.

Example

open Timed

let _ =
  let r1 = ref 0  in
  let r2 = ref 42 in

  let t1 = Time.save () in

  r1 := 73;

  let t2 = Time.save () in

  Time.restore t1;
  assert(!r1 = 0 && !r2 = 42)
  
  r1 := 17;

  Time.restore t2;
  assert(!r1 = 73 && !r2 = 42)
