이 스킬은 Rust의 가변성(mutability) 문제를 해결하기 위해 설계된 필수 도구입니다. 주요 트리거로는 E0596, E0499, E0502와 같은 컴파일 오류와 "cannot borrow as mutable", "already borrowed as immutable" 같은 일반적인 오류 메시지가 포함됩니다. 이 스킬은 Cell, RefCell, Mutex, RwLock을 사용한 내부 가변성 패턴을 비롯해 mut 키워드와 &mut 참조자와 관련된 복잡한 대여 규칙을 진단하고 수정합니다. Rust의 소유권 및 대여 시스템에 대한 깊은 이해를 바탕으로, 불변 참조가 이미 존재할 때 변경 가능한 대여를 시도하거나 여러 변경 가능한 대여를 생성하는 등의 충돌 상황을 해결합니다. 이 스킬은 Rust 컴파일러의 엄격한 가변성 규칙을 효과적으로 탐색하고, 올바른 동시성 제어를 보장하기 위해 적절한 불변 가변성 래퍼를 적용하는 방법을 안내합니다.
