From 8e29cb575f4534c4c723699164db7315a970f1ec Mon Sep 17 00:00:00 2001 From: Robin Krahl Date: Tue, 7 Jan 2020 15:22:20 +0000 Subject: Remove unused code after structopt transition In the previous patches, we replaced argparse with structopt and removed the argparse dependency. This patch removes the code that was only needed for argparse. --- src/arg_util.rs | 115 -------------------------------------------------------- src/args.rs | 90 ++++++++++++++------------------------------ src/main.rs | 1 - 3 files changed, 29 insertions(+), 177 deletions(-) diff --git a/src/arg_util.rs b/src/arg_util.rs index dbb9ce1..52d1020 100644 --- a/src/arg_util.rs +++ b/src/arg_util.rs @@ -33,35 +33,6 @@ macro_rules!
