@xtqqczze thank you for the PR!

criterion v0.8 introduces an MSRV of 1.86 [..]

Then why not upgrade MSRV to 1.86 directly?

Then why not upgrade MSRV to 1.86 directly?

I didn't want to block hashbrown v0.17.0 for crates still on 1.85.

However since dev-dependencies are not used when compiling a package for building, it might be OK to upgrade criterion while keeping MSRV of 1.85?

@xtqqczze I thought we released v0.20 so that we can make a clean cut. People relying on an older Rust version can still depend on v0.20.

Rust 1.85 was released on Feb. 20, 2025. Quite some time to adjust your own toolchain in my honest opinion. :)

I do agree, does this mean till could get merged soon?
While I don't care about the edition bump to 2024 in this PR, closing the issue for the outdated hashbrown would be nice.

LGTM and thank you for the PR!
Next time please put formatting changes in a separate PR even if that means that CI won't be happy for one PR. Makes otherwise trivial changes harder to review.
