At its core, a stream is just a sequence of data that arrives over time. You don't have all of it at once. You process it incrementally as it becomes available.
Async functions compose with Result and ? from Chapter 10 — await resolves the future, then ? unwraps the result. Use all() when you have independent operations that can run in parallel. Use race() for timeouts and fallback strategies. Use spawn only for side effects you don’t need to track. The runtime manages the event loop; your job is to describe what depends on what.
