…_with_derive, r=<try> built-in derive: remove BYTE_SLICE_IN_PACKED_STRUCT_WITH_DERIVE hack and lint Fixes rust-lang#107457 by turning the lint into a hard error. The lint has been shown in future breakage reports since Rust 1.69 (released in April 2023). Let's see (via crater) if enough time has passed since rust-lang#104429, and unicode-org/icu4x#2834 has propagated far enough to let us make this a hard error. TODO: actually remove the lint.

The crater results include multiple "no space left on device" and ld bus errors, which are familiar failures. There are also a few where the newer run fails despite only warnings being emitted, e.g. this one. And this one where the newer run has two warnings while the old run has only one warning. So, a handful of screwy results but they seem entirely unrelated to this PR. And the code changes look fine. @bors r+ |
