Streaming implementation question: using get_fast_api vs using streaming implementation page

[kanlanc]

I see there are two ways to do streaming one is run_sse from get_fastapi and the other is https://google.github.io/adk-docs/streaming/custom-streaming/

Just to be sure on my own implementation, is one better than the other in any way?

SSE is server-side streaming(which is one way streaming from server to client).

BIDI is bi-directional streaming.
