# Which issue does this PR close? - None. # Rationale for this change BitChunks used unchecked usize arithmetic when validating bit offset plus length. In optimized builds, very large lengths could wrap this bounds check before constructing the iterator state. # What changes are included in this PR? This adds checked arithmetic for BitChunks bounds validation # Are these changes tested? Yes. This adds regression coverage for overflowing bit offset plus length validation. # Are there any user-facing changes? Invalid BitChunks inputs whose offset and length cannot be represented without overflow now panic consistently. There are no API changes.
