A motion to postpone a trial, on the ground of the absence of evidence, shall only be made upon affidavit showing the materiality of the evidence expected to be obtained, and that due diligence has been used to procure it. The court may also require the moving party to state upon affidavit the evidence which the moving party expects to obtain; and if the adverse party thereupon admit that such evidence would be given and that it be considered as actually given on the trial, or offered and overruled as improper, the trial shall not be postponed.
