Rust async/await vs Go goroutines
WHAT IT TESTS: async execution models. OUTLINE: Go schedules goroutines on a built-in runtime transparently; Rust futures are inert until polled by an external runtime like Tokio, and async colors functions.
WHAT IT TESTS: whether you understand cooperative async versus a managed goroutine scheduler. ANSWER OUTLINE: Go ships an M:N scheduler in the runtime; you write blocking-looking code and goroutines are cheap, preemptible, and scheduled automatically. Rust async functions return Futures that do nothing until a runtime like Tokio polls them; there is no built-in runtime. Function coloring means async and sync functions are distinct: sync code cannot await, so async tends to spread.
