Concurrent TCP server: Go goroutines vs Rust std::thread
WHAT IT TESTS: stdlib networking and concurrency. OUTLINE: both accept in a loop; Go spawns a goroutine per connection (go handle(conn)); Rust spawns an OS thread (thread::spawn moving the stream).
WHAT IT TESTS: ability to build a basic concurrent server with each language's standard primitives and to note the cost difference. ANSWER OUTLINE: in Go, net.Listen then a loop of ln.Accept, launching go handleConn(conn) per client; goroutines are cheap and runtime-scheduled. In Rust, TcpListener::bind then iterate incoming, and for each stream call thread::spawn with move to take ownership. Rust std threads are real OS threads, so unbounded spawning is risky. RED FLAG: treating std threads as free or forgetting to move the stream.
