Get Criterion building with --minimal-versions

[Eh2406]

This is a start on #183. It gets Criterion to build with --minimal-versions! It has been a long road to get here, but in the process a large number of your dependencies got working with it.

In order to close #183 we would need to add it to CI. Do to the complexity of your CI I did not see how to do that. Suggestions are welcome. Pryor art includes: Cargos CI and walkdir CI

Awesome, thanks! I can handle the CI updates.

I notice that you've updated handlebars - is this necessary for the minimal-versions build to work? The reason I ask is because that version of handlebars (or more specifically, the transitive dependency on pest) doesn't build on Rust 1.20. Technically, Criterion.rs doesn't have to maintain compatibility with 1.20, but I don't want to break that compatibility if I don't have to.

[Eh2406]

That is a frustrating situation. The update to handlebars was made to include this PR and each line of that diff is its own PR including this PR to pest_derive.

[bheisler]

Ah, I see. That's unfortunate.

In that case, I think I'd rather put this on hold for now. I don't think it makes sense to break compatibility over something like minimal-version support, but I will definitely merge this in next time I have to break compatibility for some other reason.

Thanks again for the help!

The problems with 1.23 should be fixed now. closing and reopening to trigger new CI.

Looks good to me! Thanks for all the hard work.
