Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Safety: Unsafe pointer manipulation using non-overlapping copies and uninitialized memory (`MaybeUninit`) can lead to out-of-bounds memory access and undefined behavior if buffers are not strictly validated. Replacing these with safe primitives prevents memory corruption.
Memory Safety: Implementing performance-critical iterator traits like `BytesIter` without proper safety guarantees allows safe code to trigger undefined behavior via incorrect pointer offsets. Marking the trait itself as `unsafe` ensures the compiler forces developers to guarantee implementation invariants.
