Bump msrv to 1.85

[NobodyXu]

Debian 13 has released with rustc 1.85

I hope this won't be merged/released for a few more months.

I agree that we should at least wait for weeks, at least until many has migrated to debian 13

Is Debian the only consideration?

RHEL 8/9/10 only have 1.84 right now, but they'll be upgraded in the next minor release, around November.

Thanks, it sounds good to wait until then

Todo

• change max_by to max_by_key
• use std::sync::OnceLock

looks like msrv 1.70 is more reasonable, it contains many stdlib API we want

The logic is flawed. The fact that a specific vendor released a thing doesn't mean that a) everybody is running the same distro, b) everybody immediately upgrades. If anything, the community is better served if the decision is governed by when releases go out of support, not by when they are released.

I'm not planning to merge this PR right now, it's going to be months before it's merged

The relevant zulip discussion.

The relevant zulip discussion.

Relevant question is if those minority users are simply being obtuse or have no choice. I for one have no choice when I target ARM Morello. They have updated to 1.72 in September. From 1.56. But of course you don't have to care :-) But I do pledge implore you to not assume that everybody runs Debian and is about to upgrade.

Yes we would probably bump msrv to 1.70 instead, in 6-12 months or even longer
