rust-ownership

What problem does it solve?

This Skill helps Rust developers reason about ownership, borrowing, and lifetimes to prevent common memory-safety mistakes and to write clearer, more efficient code.

Core Features & Use Cases

• Pattern 1: Move vs Clone vs Copy — choose the right ownership model to control data movement and avoid unnecessary cloning.
• Pattern 2: Borrowing Rules — manage immutable and mutable borrows to enable safe, concurrent access.
• Pattern 3: Lifetimes in Functions and Structs — annotate and apply lifetimes to ensure references are valid across scopes.
• Pattern 4: Smart Pointers for Shared Ownership — use Rc/Arc and RefCell/Mutex for interior mutability and thread-safe sharing.
• Pattern 5: Avoiding Common Pitfalls — recognize when to clone, borrow, or restructure to prevent runtime or compile-time errors.
• Use Case Example: Refactor a function to take a borrowed reference instead of transferring ownership to avoid unnecessary moves.

Quick Start

Install or ensure a Rust toolchain is available, then review the included examples and refactor your code by applying ownership, borrowing, and lifetime patterns. Run cargo build and tests to verify safety and correctness.
