[tnull]

We run rustfmt on the fuzz dir and make sure that any auto-generated targets are formatted, too.

Should be good for initial reviews.

Do you want to go ahead and land all the "simple" stuff (ie everything but full_stack and chanmon_consistency) here and do the rest in a separate PR?

Now split them out to https://github.com/lightningdevkit/rust-lightning/pull/3111 and rebased this on top.

[tnull]

Rebased after #3111 landed and addressed open comments.

Alright, would you prefer that we put this PR on hold until #3113 is merged? I'll mark this as blocked on dependent PR for now and will review #3113 ASAP to keep making progress.

If that's alright. Its more annoying to rebase that than rustfmt...
