From 6cae9704af80f6ffbca2770c5bbf9ab94ef846f8 Mon Sep 17 00:00:00 2001 From: Daniel Mueller Date: Wed, 16 Jan 2019 17:41:15 -0800 Subject: Remove no longer required dependencies With the update to rand 0.6.4 we no longer require the dependencies to rustc_version, semver, and semver-parser. Hence, this change removes them.
