Rust borrow rules versus Go race prevention
WHAT IT TESTS: how each language stops data races. OUTLINE: Rust's aliasing-XOR-mutability rule plus Send and Sync make races a compile error; Go prevents them at runtime via channels, mutexes and the race detector.
WHAT IT TESTS: whether you connect Rust's borrow rules to compile-time race freedom and know Go's runtime-based discipline. ANSWER OUTLINE: Rust allows either one mutable reference or many shared references but never both, so no thread can write while another reads the same data; Send and Sync extend this across threads, making races a compile error. Go has no such guarantee; you avoid races by sharing via channels, guarding shared state with sync.Mutex, and validating with the runtime race detector.
