Implement deterministic resource cleanup in Rust using the Drop trait and RAII patterns. This Skill provides ready-to-copy examples for Drop and custom scope guards to ensure automatic, leak-free resource release.

The best way to lazily initialize resources in Rust is using OnceLock or LazyLock. This Skill offers implementation snippets and when-to-use guidance for integrating these structures into your modules for safe, deferred initialization.

Set up a connection pool in Rust by applying guard patterns to manage checkout and release. This Skill provides pattern library tables and anti-pattern guidance to help you implement safe pooling with deterministic cleanup behavior.

Rust resource leaks despite RAII often stem from cyclic references or incorrect Drop implementations. This Skill outlines common pitfalls, anti-patterns, and safer alternatives to diagnose and prevent resource leaks in your application.

You need custom guard structures in Rust when standard RAII does not cover complex resource handoffs. This Skill maps high-level design questions to concrete Rust constructs, guiding you on when to implement scope guards for deterministic cleanup.

Yes, this Skill applies to Rust projects requiring lifecycle management across modules. It provides domain mapping to trace high-level design questions to concrete Rust constructs like Drop and LazyLock for cross-module resource cleanup.
