Use as `response_class=EventSourceResponse` on a *path operation* that uses `yield` to enable Server Sent Events (SSE) responses. Works with **any HTTP method** (`GET`, `POST`, etc.), which makes it compatible with protocols like MCP that stream SSE over `POST`. The actual encoding logic lives in the FastAPI routing layer. This class serves mainly as a marker and sets the correct `Content-Type`. ztext/event-streamN)__name__ __module__ __qualname____firstlineno____doc__ media_type__static_attributes__rH/home/mande/repo/quber/.venv/lib/python3.13/site-packages/fastapi/sse.pyrrs %Jr!rvN field_namereturncBUbSU;dSU;a[SUS35eU$)N  zSSE 'z' must be a single line) ValueError)r#r$s r"_check_single_liner*$s-}$!)tqy5 ,CDEE Hr!c[US5$)Nr)r*r#s r"_check_event_single_liner-*s a ))r!cBUbSU;a [S5e[US5$)Nz)SSE 'id' must not contain null charactersr)r)r*r,s r"_check_id_validr0.s&}DEE a &&r!cR\rSrSr%SrSr\\\"S54\ S'Sr \\ S-\"S54\ S'Sr \\ S-\ "\5\"S54\ S 'Sr\\ S-\ "\5\"S 54\ S 'Sr\\S-\"S S 9\"S54\ S'Sr\\ S-\"S54\ S'\"SS9SSj5rSrg)ServerSentEvent4aLRepresents a single Server-Sent Event. When `yield`ed from a *path operation function* that uses `response_class=EventSourceResponse`, each `ServerSentEvent` is encoded into the [SSE wire format](https://html.spec.whatwg.org/multipage/server-sent-events.html#parsing-an-event-stream) (`text/event-stream`). If you yield a plain object (dict, Pydantic model, etc.) instead, it is automatically JSON-encoded and sent as the `data:` field. All `data` values **including plain strings** are JSON-serialized. For example, `data="hello"` produces `data: "hello"` on the wire (with quotes). NaB The event payload. Can be any JSON-serializable value: a Pydantic model, dict, list, string, number, etc. It is **always** serialized to JSON: strings are quoted (`"hello"` becomes `data: "hello"` on the wire). Mutually exclusive with `raw_data`. raQ Raw string to send as the `data:` field **without** JSON encoding. Use this when you need to send pre-formatted text, HTML fragments, CSV lines, or any non-JSON payload. The string is placed directly into the `data:` field as-is. Mutually exclusive with `data`. raw_dataz Optional event type name. Maps to `addEventListener(event, ...)` on the browser. When omitted, the browser dispatches on the generic `message` event. Must be a single line. rz Optional event ID. The browser sends this value back as the `Last-Event-ID` header on automatic reconnection. **Must be a single line** and must not contain null (`\0`) characters. rr)gez Optional reconnection time in **milliseconds**. Tells the browser how long to wait before reconnecting after the connection is lost. Must be a non-negative integer. rz Optional comment line(s). Comment lines start with `:` in the SSE wire format and are ignored by `EventSource` clients. Useful for keep-alive pings to prevent proxy/load-balancer timeouts. commentafter)modecPURbURb [S5eU$)NzCannot set both 'data' and 'raw_data' on the same ServerSentEvent.
