Failure is due to MSRV 1.70 (June 2023) not being new enough, due to an implicit dependency from the rust-ini release 0.20 (Oct 18th) via ordered-multimap raised MSRV to 1.71 (July 2023), as ordered-multimap released 0.7.1 (Oct 25th) with a feature that is unstable on earlier rust toolchains.

This wasn't something rust-ini could catch, as their 0.20 release bumped that dependency from 0.6 (Jan 2023) to 0.7 (Aug 24th). Just a result of semver resolution, technically ordered-multimap should not have released that change as a patch release? 🤷‍♂️

Raised bug reports:

• Document Rust MSRV of 1.71 requirement for release 0.7.1 sgodwincs/ordered-multimap-rs#26
• 0.20 release implicitly raised MSRV of rust-ini to 1.71 (July 2023) zonyitoo/rust-ini#117

In the meantime, I guess keep rust-ini at 0.19 and wait to see what happens upstream?

Yes, that's what I'd do, at least as long we do not have a release coming up.
I wonder what will happen with our next patch release, whether we need to restrict versions for that package to stay compatible.

I have been looking into this to get a better understanding of MSRV and maintenance of Cargo.toml / Cargo.lock with library crates and CI 👍

I will contribute some input on the recent issues / PRs related to this. Apparently raising the MSRV on point releases isn't uncommon in the rust ecosystem? 🤷‍♂️

It does seem like adopting rust-version would be wise though.
