From c09b9f937250db0f51b705a3110f8cffdad083bb Mon Sep 17 00:00:00 2001 From: Simon Sapin Date: Sat, 17 Mar 2018 12:15:24 +0100 Subject: [PATCH] Deprecate the AsciiExt trait in favor of inherent methods The trait and some of its methods are stable and will remain. Some of the newer methods are unstable and can be removed later.
