From fd141bbed2a900070cbecf7ef9f22e377e1f353f Mon Sep 17 00:00:00 2001 From: Savil Srivastava Date: Thu, 19 Jul 2018 17:26:27 -0700 Subject: [PATCH] [Error] rename msg field to action this was a TODO and also briefly discussed in https://github.com/rust-bitcoin/rust-lightning/pull/43#pullrequestreview-135649551 I'm not fully sure how to remove the `Option`, and make it completely required. Would love suggestions. So, have omitted that for now. Plus, better to make smaller, incremental changes.
