Compilation failure on nightly rust

[kurtlawrence]

I tried this code

Nightly: nightly-x86_64-unknown-linux-gnu unchanged - rustc 1.78.0-nightly (4a0cc881d 2024-03-11)

cargo +nightly check -F serialize

Results in compilation error:

error[E0275]: overflow evaluating the requirement `&_ well-formed`
   --> src/util.rs:445:13

Possibly related to #45, but a fix will be required for debug.

I'd like to +1 this. My CI runs over in cstree started to fail due to this issue 2 months ago because anything that runs on nightly no longer compiles.

Happy to help with a fix, though I can't quite make out what's the issue with / required beyond #45.

I believe this has now hit stable

[ThePseudo]

I confirm, the problem hit Rust stable.

If nobody else wants to, I can fork and publish a maintained version with some of the outstanding PRs merged?

[silvanshade]

I published a fork at lasso2 with a fix for this. I will try to keep it maintained so contributions are welcome.
