📝 Walkthrough

Walkthrough

Refactors the row-collection loop in the SQLite fetchmany method to use an explicit remaining-count variable and match on Cursor::next instead of breaking when max_rows count is reached. The control flow now handles StopIteration explicitly with equivalent functionality but clearer iteration semantics.

Changes

Cohort / File(s) Summary
SQLite Fetchmany Loop Refactor
crates/stdlib/src/_sqlite3.rs		 Replaces implicit row-collection loop with explicit remaining-count and Cursor::next match pattern; handles StopIteration directly while maintaining equivalent behavior and error handling.

Poem

🐰 A loop that once danced in ambiguity's hue,
Now marches with clarity, remaining count true,
No StopIteration shall catch us unaware,
Control flow explicit, refactored with care! ✨
