Detailed Description

The top-level frame exchanged between two A11 endpoints.

Batches any number of a11::data::NodeFragment payloads and a11::data::ActionMessage invocations together with connection-level headers into a single unit sent across a stream. A half-close message (see MakeHalfCloseMessage) is a WireMessage that signals the sender is done writing.
