Hey @leynos - I've reviewed your changes - here's some feedback:
- The permission denied test uses a hardcoded
/procpath which isn't portable; consider creating a temp file and removing write permissions for a more reliable cross‐platform test. - Consider adding similar error‐case tests for
rewrite_no_wrapto ensure it exhibits the same IO error behavior asrewrite.

## Overall Comments
- The permission denied test uses a hardcoded `/proc` path which isn't portable; consider creating a temp file and removing write permissions for a more reliable cross‐platform test.
- Consider adding similar error‐case tests for `rewrite_no_wrap` to ensure it exhibits the same IO error behavior as `rewrite`.

<code_context>
let lines: Vec<String> = text.lines().map(str::to_string).collect();
- let fixed = process_stream(&lines);
+ let fixed = f(&lines);
fs::write(path, fixed.join("\n") + "\n")
}
</code_context>
<issue_to_address>
Appending a newline unconditionally may introduce an extra newline if the processed content is empty.
If `fixed` is empty, the file will contain only a newline. Consider appending the newline only when `fixed` is not empty, if that's the desired behavior.

7-27: Excellent extraction of common logic with proper error handling.The
rewrite_withhelper function successfully eliminates code duplication whilst properly addressing the previous review concern about empty file handling. The generic design allows both processing functions to share the same I/O logic.The documentation is clear and follows Rustdoc conventions. The function correctly handles the empty output case by writing an empty string rather than a newline, which addresses the past review comment.
33-33: Clean single-line function implementation.The refactored
rewritefunction correctly follows the coding guideline of not usingreturnin single-line functions. The delegation torewrite_withmaintains the same public API whilst benefiting from the shared implementation.
39-41: Consistent refactoring maintains API contract.The
rewrite_no_wrapfunction is consistently refactored to use the same helper pattern. The implementation is clean and maintains the existing function signature and behaviour.
45-50: Platform-specific imports are properly organised.The conditional imports are well-structured with appropriate
#[cfg(unix)]attributes. Thelibcimport is correctly scoped to Unix platforms wheregeteuid()is available.
75-81: Thorough error testing for missing files.The test correctly verifies that missing files produce
NotFounderrors. The test setup and assertions are appropriate.
104-110: Consistent error testing for the no-wrap variant.The test maintains consistency with the wrapped variant whilst ensuring both functions handle missing files identically.
133-141: Essential test for empty file behaviour.This test directly addresses the past review comment concern about empty files adding unwanted newlines. The test correctly verifies that empty files remain empty after processing.
