From: Jeffrey Czyz Date: Tue, 19 Sep 2023 15:59:53 +0000 (-0500) Subject: Rename OnionMessageContents X-Git-Tag: v0.0.118~11^2~8 X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=94573dda33c2e6bf55b2f28ffe7fbdf0a37f6edc;p=rust-lightning Rename OnionMessageContents In preparation for needing the name OnionMessageContents for a trait to bound methods, rename it to ParsedOnionMessageContents. In the next commit, it's use will be limited to reading only, and the new trait will be a bound on method parameters instead. --- diff --git a/lightning/src/onion_message/functional_tests.rs b/lightning/src/onion_message/functional_tests.rs index 33aebb0fd..319417e80 100644 --- a/lightning/src/onion_message/functional_tests.rs +++ b/lightning/src/onion_message/functional_tests.rs @@ -15,7 +15,7 @@ use crate::ln::msgs::{self, DecodeError, OnionMessageHandler};
