zerocopy-derive@0.8.50

zerocopy-derive 0.8.50 is the proc-macro companion to zerocopy: 10 derives (KnownLayout, Immutable, TryFromBytes, FromZeros/FromBytes, IntoBytes, Unaligned, ByteHash, ByteEq, SplitAt) emitting unsafe-trait impls based on type shape and #[repr(...)]. Source matches upstream byte-for-byte. The proc-macro runs pure safe Rust — no I/O, no unsafe in its executable path. Coverage is broad: 35 integration tests, 26 trybuild UI tests, 21 golden-output tests. No findings.

zerocopy-derive@0.8.48

zerocopy-derive 0.8.48 is a procedural-macro crate emitting derives for zerocopy traits. The proc-macro runtime is a pure AST-to-TokenStream function with a single documented unsafe fn whose body is safe Rust. No findings; safe to deploy.
