C++와의 상호운용성

CXX 크레이트는 러스트와 C++ 사이의 안전한 상호운용성을 가능하게 해줍니다.

전체적인 접근 방법은 다음과 같습니다:

사용하는 방법에 대해서는CXX 튜토리얼 를 참조합니다.

  • At this point, the instructor should switch to the CXX tutorial.

  • Walk the students through the tutorial step by step.

  • Highlight how CXX presents a clean interface without unsafe code in both languages.

  • Show the correspondence between Rust and C++ types:

    • Explain how a Rust String cannot map to a C++ std::string (the latter does not uphold the UTF-8 invariant). Show that despite being different types, rust::String in C++ can be easily constructed from a C++ std::string, making it very ergonomic to use.

    • Explain that a Rust function returning Result<T, E> becomes a function which throws a E exception in C++ (and vice versa).
