From: Jeffrey Czyz Date: Fri, 13 Oct 2023 22:01:19 +0000 (-0500) Subject: Use ChainHash instead of BlockHash as applicable X-Git-Tag: v0.0.118~15^2 X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=54f96ef944423eac98d302fbc7cdcdc136d58312;p=rust-lightning Use ChainHash instead of BlockHash as applicable ChainHash is more appropriate for places where an arbitrary BlockHash is not desirable. This type was introduced in later versions of the bitcoin crate, thus BlockHash was used instead. Using ChainHash also makes it easier to check if ChannelManager is compatible with an Offer. --- diff --git a/fuzz/src/full_stack.rs b/fuzz/src/full_stack.rs index d7167146c..9ed58dd94 100644 ---
