For Rust error handling, choose thiserror for library-grade custom error types and anyhow for application-grade error propagation with context. This skill provides decision guidance for mixed crates to ensure consistent error management across your project.

Select tokio for standard multi-threaded async workloads and embassy for embedded runtime constraints. This skill recommends the appropriate async executor or simpler blocking alternatives based on your specific workload and system limitations.

Managing Rust ownership requires clarifying when to use moves, borrows, Rc, or Arc, alongside interior mutability like RefCell, Mutex, or RwLock. This skill maps your concurrency scenarios to the correct safety-oriented ownership patterns.

To fix failing Rust tests and clippy warnings, apply implementation heuristics and verification checklists including fmt, clippy, test, and audit gates. This skill helps debug code by mapping scenarios to robust patterns like newtypes and builders.

Yes, this Rust guidance applies to the 2024 edition, emphasizing common robust patterns such as newtypes, builder type-state, and iterator practices. It ensures your library, binary, or mixed-crate codebase follows modern safety-oriented verification.
