How does this skill help with Rust E0382 errors?

It analyzes the data's domain role to determine if a value should be moved, cloned, or if the ownership design should be restructured for better resource management.

Does it just suggest using .clone() to fix errors?

No, it treats indiscriminate cloning as an anti-pattern and guides you toward the most efficient architectural fix, such as using references or smart pointers.

When should I use the m01-ownership skill?

Trigger this skill when the Rust compiler flags ownership, borrowing, or lifetime violations that require more than a simple syntax fix.

Can it help with complex lifetime annotations?

Yes, it provides logic for mapping actual lifetime relationships and helps place 'a annotations correctly instead of guessing.

Developer Tools

Resolves complex Rust memory management issues by analyzing ownership, borrowing, and lifetime constraints.

About

This skill empowers Claude to navigate the intricacies of the Rust borrow checker by providing structured guidance on ownership, borrowing, and lifetime management. Instead of applying surface-level fixes like indiscriminate cloning, it uses a design-first approach to determine data roles—distinguishing between Entities and Value Objects—and provides strategic paths for resolving specific compiler errors such as E0382, E0597, and E0106. It is an essential tool for developers refactoring resource-heavy code, debugging persistent lifetime issues, or transitioning between single-threaded and concurrent architectures.

Key Features

Targeted resolution for Rust compiler errors like E0382, E0597, and E0506
Strategic decision-making for Move vs. Borrow vs. Clone implementation patterns
Smart pointer selection including Rc, Arc, and Cow based on thread-safety needs
Prevention of memory leaks and anti-patterns like excessive .clone() or Box::leak
596 GitHub stars
Lifetime annotation guidance and 'a parameter optimization

Use Cases

Debugging 'value moved' and 'borrowed value does not live long enough' errors
Refactoring single-threaded code to multi-threaded environments using Arc/Mutex
Designing efficient data structures that minimize heap allocation and copying
