I'd love to see this move forward; @fmckeogh could you fix these errors or would you be amenable to my opening another PR that passes CI? Thanks for starting this.

@ahl Of course! Sorry I missed the errors, doing it now:)

@ahl All except 1.37.0 passing due to updating indexmap. Should I revert this to 1.6.2 or update the pinned version being used in CI?

I would suggest leaving indexmap at 1.6.2. I think the most useful of your changes are the ones you noted in this PR description: uuid, arrayvec, and (maybe) pretty_assertions

@ahl Fixed, but unfortunately it looks like UUID 1.0.0 requires rustc 1.46.0 or newer. What would you like to do?

Hello! First thank you for your pull request, I have written the same. As uuid need at least rust 1.46.0 and we are at rust 1.60.0, maybe it is time to move the msrv to at least the uuid one?

@GREsau what do you think of bumping the minimum required rustc version from 1.37 to 1.46?

I don't think I can merge this as-is even if I do increase MSRV and tests to 1.46+, as this change will break backward compatibility. Any users currently using the old versions of uuid/arrayvec with the corresponding features of schemars will be broken.

I've whipped up an alternative change in #142 which supports the newer crate versions in a backward-compatible manner, specifically by requiring the new feature flags uuid1/arrayvec07 to be enabled.

I presume this would be sufficient for what you need? If so I'll finish and merge it

Sounds good to me:) Closing in favour of #142
