asyncio: Transports Move Bytes, Protocols Decide Which Bytes
asyncio Transports are the "how" (moving bytes), while Protocols are the "what" (deciding which bytes to send). They're the low-level foundation for libraries handling raw socket I/O.
Think of asyncio Transports as the delivery truck (how bytes move) and Protocols as the manifest (what bytes to send and how to process arrivals). A transport abstracts the raw socket, while the protocol implements your application's logic via callbacks. This model is for library authors building high-performance network tools, like an HTTP client or database driver. The footgun: application developers should avoid them; stick to high-level async/await stream APIs, which are built on top of these primitives.
