📝 Walkthrough

Walkthrough

Configuration update to ignore a Rust security advisory in deny.toml, and a refactoring in the idastar module that changes the sorting algorithm from tuple comparison to single-key sort by cost value.

Changes

Cohort / File(s) Summary
Configuration
deny.toml
Added advisory ID RUSTSEC-2025-0141 to the ignore list in [advisories] section
Sorting Refactoring
src/directed/idastar.rs
Replaced tuple-based comparator with sort_unstable_by_key that sorts exclusively by the cost field (third element), changing tie-breaking behavior

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~12 minutes

Poem

🐰 A hop and skip through sorting trails so fine,
We pluck just the cost, no need to align,
And whisper "ignore" to that advisory sound—
Cleaner paths emerge from the rabbit's ground! 🌿
