Nothing interesting, just make [a]rc code a little nicer by using byte_sub and let-else.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

I'm not sure this is a change we want to make. There's an ongoing effort in #94971 and #94970 to reduce the number of unstable features used by the stdlib -- at least outside of libcore, and/or where not necessary.

As for where we can use these features in order to test them out / bikeshed them before landing, I think the idea is that the compiler is a better place for this than the stdlib (and hopefully they agree!), so that might be a better place to try a PR like this.

@thomcc Thanks for clarifying libs team intentions! I can remove the added use of let-else.

I think that byte_sub change is still meaningful though (+ I plan to propose stabilizing it, so it won't be unstable for long, hopefully :D).

At the very least, it would likely be a good idea to make an experience report comment linking to this PR on the byte_sub tracking issue -- IMO, the code is definitely nicer and more readable with it.

Update: rebased to remove let-else commit.
