async/await
Syntactic sugar for asynchronous programming in Rust, based on cooperative scheduling. It implements task suspension and resumption through state machine transformations and is suited for I/O-intensive concurrent scenarios.
Timeline (last 90 days)
Running AgentScope requires the use of asynchronous programming (async/await): conversation methods must be defined with async def, await is used where the model is called, and at startup an asynchronous entry point such as asyncio.run() must be used; it cannot be called directly in a synchronous manner.
Cooperative scheduling means concurrent tasks voluntarily yield execution rather than being forcibly preempted by the operating system; in the async/await model, the runtime maintains an event loop, and a task suspends itself and returns control when it hits an await, and if a task occupies the CPU for a long time without awaiting, the entire event loop is blocked.
The async/await syntactic sugar allows developers to write asynchronous code in a near-synchronous manner, improving the readability issues of callback hell and Promise chains.
The function coloring problem refers to the fact that once a function is marked as async, the functions that call it often also need to become async, making it contagious.
Compared to asyncio coroutine solutions, the advantage of threads is that code does not need to be rewritten in async/await style, existing synchronous libraries can be used directly, and the learning curve is gentler.
