) -> Result<BoxBody, SerdeError>Expand description
Builds the response body of an event stream output: the marshalled events, preceded by an
initial-response frame when initial_response is InitialResponsePolicy::Send.
Protocols that carry non-stream members in initial messages serialize those members into the frame. HTTP-bound protocols use their unset payload instead, matching generated serde servers.
output_schema and output describe the non-stream members; the streaming member must
already have been moved out of output into events.
