Potential zero-padding issue in hexadecimal output

Category
Correctness
Code Snippet
sb.write_string(b.to_int().to_string(radix=16))
Recommendation
Use zero-padding to ensure consistent 2-digit hex format: b.to_int().to_string(radix=16).pad_start(2, '0')
Reasoning
The original code manually handled each hex digit to ensure 2-character output (e.g., '0a' instead of 'a'). The new implementation may produce single-digit hex values for bytes < 16, which could break parsing or display expectations.

Inconsistent hex formatting between Unicode and byte escapes

Category
Correctness
Code Snippet
logger..write_string("\u{")..write_string(code.to_string(radix=16))..write_char('}')
Recommendation
Consider padding Unicode hex values: code.to_string(radix=16).pad_start(expected_width, '0')
Reasoning
Unicode escape sequences typically expect consistent formatting. While not necessarily incorrect, the original manual digit approach ensured predictable output length.

Good refactoring that eliminates code duplication

Category
Maintainability
Code Snippet
Removal of to_hex_digit function and its usage across multiple files
Recommendation
Consider adding unit tests to verify hex formatting behavior remains consistent
Reasoning
The refactoring successfully removes a custom utility function in favor of standard library functionality, improving maintainability. However, the behavioral change in padding should be tested to ensure compatibility.

Missing zero padding here.
