class RestStream

SSE stream for the HTTP+JSON/REST binding.

Per the A2A spec, REST streaming returns SSE where each data: line is a bare StreamResponse JSON object (no envelope wrapping).

This is essentially just an alias for Stream — the base class already emits bare JSON. We keep this as a named class for symmetry with JsonRpcStream and to make binding code self-documenting.

Usage:

stream = A2A::SSE::RestStream.new

Async do stream.event("task" => { ... }) stream.finish end
