Fix lifetime and ownership errors in async Rust by ensuring borrowed data outlives async tasks and moving owned values across await points. This Skill guides ownership management and concurrency with tokio to produce memory-safe, idiomatic asynchronous services.

Design flexible trait hierarchies and generic APIs in Rust using trait objects and bounds to build zero-cost abstractions. This Skill provides patterns for trait-based API design, enabling polymorphic interfaces without runtime overhead while enforcing Rust 2021 practices.

Handle errors in Rust using Result and Option types combined with thiserror for library-specific errors and anyhow for application-level flexibility. This Skill enforces safe error handling patterns to ensure robust systems programming and reliable error propagation.

This Rust guidance supports creating FFI bindings and explicitly minimizes unsafe code blocks to guarantee memory safety. It promotes zero-cost abstractions and high-performance code execution while maintaining strict safety guarantees across systems programming tasks.

Use cargo fmt for code formatting and cargo clippy for linting as part of a strict testing discipline in Rust development. This Skill enforces these practices alongside robust testing strategies to ensure idiomatic code quality and maintain reliable systems.
