inplace-iter crate #2337
Description
The crates.io support email got a report about inplace-iter
so I'm handing this over to you. Please let us know if there's any action you think crates.io should take!
This crate uses unsafe code to directly create undefined behavior
An issue has been created, but there has been no response within two weeks
Looks like the reporter has actually filed 2 issues on inplace-iter's repo:
The reporter also included this `miri test --workspace --no-fail-fast` output
Finished `test` profile [unoptimized + debuginfo] target(s) in 0.03s
