などの構造要素を含 む現代的な言語です。 • Experience with Java, Go, Python, JavaScript...: You get the same memory safety as in those languages, plus a similar high-level language feeling. In addition you get fast and predictable { let mut s = String::from("careful!"); let r1 = &raw mut s; let r2 = r1 as *const String; // SAFETY: r1 and r2 were obtained from references and so are guaranteed to // be non-null and properly aligned add_to_counter(inc: u32) { // SAFETY: There are no other threads which could be accessing `COUNTER`. unsafe { COUNTER += inc; } } fn main() { add_to_counter(42); // SAFETY: There are no other threads

associate several different types of data with an enum, such as a character. This gives stricter type safety, for example, when it might be possible to accidentally convert a variable into a numeric type. For cppreference.com/w/cpp/language/enum Drawbacks: Virtually none. Very small changes to the code, more type safety, removes the need for some tables of values. The only problem is sometimes this requires fixing code information about the process refer to the Testing Strategy. Test Engineering The test suite is the safety net enabling the community to fearlessly move forward. We have a comprehensive testing strategy to
