- Around line 347-351: The test is using "x".repeat(33) which mismatches the
intended strict STR_LEN cap of 32; update the test to use "x".repeat(STR_LEN) or
"x".repeat(32) and adjust the expected output accordingly so it reflects a
strict STR_LEN boundary (not inclusive ..=STR_LEN); locate the assertion that
builds the expected string (the "[hex: {}..{}, str: {}]" template) and replace
the 33-length input with STR_LEN (or 32) and ensure the formatted range uses the
proper exclusive/inclusive bounds consistent with STR_LEN.
- Line 248: Replace the verbose Error::new(ErrorKind::Other, "...") usages with
the idiomatic Error::other("...") calls where errors are constructed (the
Err(...) expressions using Error::new at each occurrence), i.e. change
Err(Error::new(ErrorKind::Other, "write failure")) and the two other
Error::new(...) occurrences to Err(Error::other("...")) so the functions that
return Result use Error::other instead of Error::new; keep the same error
message strings when making the new Error::other calls.

STR_LEN truncation test currently locks in an off-by-one boundary.
Line 350 expects 33 chars, which matches ..=STR_LEN behavior, not a strict STR_LEN == 32 cap.

Addressed CodeRabbit feedback: Comment 1 (Error::other) — ✅ Fixed in 8094376. Replaced all three Comment 2 (STR_LEN truncation off-by-one) — The test correctly reflects the existing production code behavior. The production code uses |
