`rustfmt`: Run on `util/*` (2/2) #3323

tnull · 2024-09-18T07:42:13Z

This is PR 2/2, based on #3324.

The diff is a bit larger for this one, but AFAICT the changes look mostly reasonable (besides the oddity commented below).

FWIW, I had a look at currently open inflight PRs and the conflicts should be minimal if I'm not overlooking something.

Ugh, can we split this? 42 commits in one PR is just a lot...

Ugh, can we split this? 42 commits in one PR is just a lot...

Alright, happy to if you prefer (although at least half of these commits are one-line diffs). Now split out ~the first half of commits to #3324.

tnull · 2024-09-19T08:11:18Z

Rebased after #3327 landed.

tnull · 2024-10-01T16:02:30Z

Rebased after #3324 landed.

tnull · 2024-10-07T08:25:08Z

Rebased to resolve minor conflicts.

tnull · 2024-11-05T09:14:53Z

Rebased once more to resolve minor conflicts.

Any additional comments here after we landed the split-out commits in #3324, @TheBlueMatt ?

Some initial comments. Maybe could have been split across PRs.

Not sure how much readable it would be pulling out stuff here into variables? Seems that might just make stuff more confusing?

Can this be less verbose if we use self.inner.sign_holder_htlc_transaction?

Turns out I had to revert the changes as otherwise cargo would complain under cfg(taproot):

Fixed the missing unwrap and rebased on main as this PR is ancient and I wanted to ensure there were no silent conflicts in the meantime:

Good enough. Some stuff I'll clean up in a followup, some of it pre-existing.

PR lightningdevkit#3323 introduced some extra variables to avoid `rustfmt` making a total mess of our code, but introduced a few that don't make `rustfmt` do dumb things, which we remove here.
