[reneleonhardt]

Chores

• MSRV passed the 1.85 threshold, prepare for edition 2024

Notes

• All changes are fixing the stricter exhaustiveness rules
• TODO: relative drop order changing in Rust 2024
  https://doc.rust-lang.org/edition-guide/rust-2024/temporary-tail-expr-scope.html
  Run cargo fix --edition --prepare-for=2024 --allow-dirty and fix all warnings manually.

I think we do not need any changes on our current code-base at all to switch to the 2024 edition.
No need to replace all if let... with bulky match statements as far as i know.

Old code is still valid, but just try cargo fix yourself to see all warnings for changed rules.

You can see how much I improved manually to reduce that bulkiness to a minimum, that's not the same code cargo fix generated.

There is no need for cargo fix on our current code-base.
With Edition 2024 there are several other items which could be fixed like some if statements which can be merged, this can be seen when you run clippy on the code-base after setting the Edition to 2024.

All other fixes Cargo does automatically are only because it doesn't know if it will break the code or not, and just goes ahead and adjust it to a more safe default, which as far as I can tell, is not needed at all.
