rust-ownership

The rust-ownership skill serves as a specialized expert diagnostic tool for developers navigating the complexities of Rust's core memory safety model. It is designed to assist both beginners and intermediate Rust engineers in resolving frequent compiler diagnostics like E0382 (use of moved value), E0597 (lifetime too short), E0506 (borrow not ended before mutation), and E0507 (move out of reference). By providing systematic solution patterns, it shifts the focus from 'fighting the borrow checker' to understanding data ownership, scope boundaries, and the appropriate selection of smart pointers such as Box, Rc, Arc, and RefCell.

• Expert-led guidance on resolving E0382, E0597, E0506, E0507, E0515, E0716, and E0106 compiler errors.

• Practical, repeatable solution patterns for common borrow checker conflicts and lifetime mismatches.

• Strategic decision-making support for choosing between stack, heap, and shared ownership models (Arc/Rc).

• Deep analysis of interior mutability vs. standard references to optimize code safety and performance.

• Comprehensive troubleshooting for complex lifetime annotations, including handling of static lifetimes and trait bounds.

• Users should provide the failing snippet of code or the specific compiler error message for the most accurate diagnostic result.

• Typical inputs include source code, struct definitions, or function signatures that exhibit borrowing ambiguity.

• Outputs consist of refactored code suggestions, identification of ownership transfer points, and architectural advice to prevent recurring design anti-patterns.

• This skill integrates seamlessly into CI/CD development workflows by emphasizing code that is not just compliant with the compiler, but designed for long-term maintainability and performance without excessive cloning. It encourages an intentional approach to data lifetime management, ensuring that memory safety is a byproduct of sound system design rather than a persistent hurdle.
