Return bytes still buffered by the underlying transport.
Close the physical channel and release transport resources.
Expose the transport-specific object for advanced integration.
Return whether packet sends are currently possible.
Open the underlying channel and resolve when packet I/O is available.
Release callback references after full stream completion.
Queue one framing packet without waiting for physical delivery.
Install the callbacks used for one stream lifecycle.
Await a low-water notification; callers recheck bufferedAmount.
Transport-adapter seam shared by WebSocket, WebRTC, and in-process streams.
Implement this interface when bringing another message-capable binary transport to A11. ChannelWireStream supplies byte packetization, bounded out-of-order reassembly, A11 half-close/abort messages, deadlines, and callback ordering. The adapter only owns opening, packet I/O, backpressure observation, and physical closure.
