Introduce `ServerSentEvent[Data]` so endpoints that yield typed SSE events get a `contentSchema` in the OpenAPI spec reflecting the data payload type, while retaining full control over SSE fields (`event`, `id`, `retry`, `comment`). - `ServerSentEvent` now inherits from `Generic[Data]` with `data: Data` - `validate_default=True` ensures `ServerSentEvent[Item]()` raises a ValidationError (data is effectively required when Data is concrete) - `ServerSentEvent[Item | None]` allows optional data; bare `ServerSentEvent` is fully backward compatible (`Data=Any`) - Added `get_sse_data_type()` helper (uses Pydantic's `__pydantic_generic_metadata__`) to extract `Data` from a parameterized `ServerSentEvent[Data]` annotation - Routing layer now extracts `Data` from `ServerSentEvent[Data]` and uses it as `stream_item_type`, feeding it into the existing OpenAPI `contentSchema` pipeline - Added tutorial006 and corresponding snapshot test - Extended test_sse.py with generic SSE unit and app-level tests Co-Authored-By: Claude Sonnet 4.6 <[email protected]> |
