Please follow the procedure described in CONTRIBUTING.md regarding MSRV to fix the CI check.

[Lorak-mmk]

Sorry for the delay! Generally looks good. There are some changes needed.

• Please rebase on main. We no longer have Cargo.lock.msrv thanks to Rust 2024, so your last commit becomes redundant.
• Every commit should be an atomic change that passes checks and tests, and has proper description. Your third and fourth commit are fixing issues introduced by eralier commits. Instead of having new commits for that, the earlier commits should be edited to not introduce those issues in the first place. This approach also makes the review easier - we can review each commit separately, and not see issues that are fixed in some later commit.
• I'm not familiar with serde, so it is not obvious to me if the functionality you introduced works properly. Please add unit tests that demonstrate what this PR allows the user to do.
