asyncio Streams: High-Level Async Network I/O
asyncio Streams are like async file handles for the network. You get a reader/writer pair to await data, simplifying TCP clients and servers for basic protocols. The footgun: the default buffer limit is small; reading large data will fail unexpectedly.
asyncio Streams treat a network connection like an async file. Instead of low-level transports, you get a simple `(reader, writer)` pair to work with. This is perfect for building straightforward TCP clients and servers for custom protocols. The footgun: the default buffer limit is small; reading a message larger than the limit (e.g., 64KB) raises a `LimitOverrunError` instead of returning data. You must explicitly set a higher limit.
