SSE Codec

Server-Sent Events codec — event-record stream ↔ byte iterables. The encoder produces one SSE frame per item (event: <type>\ndata: <json>\n\n).

Why use this

• Drop-in for text/event-stream — register Sse.Encoder on an Http.Server to expose any async iterable as an SSE stream.
• Typed event records — items carry { event, data }, so producers stay schema-checked.
• Implements the Codec.Encoder abstract — consumers that depend on Codec.Encoder get SSE for free at the import boundary.
