[−][src]Function warp::filters::sse::sse

pub fn sse() -> impl Filter<Extract = (Sse,), Error = Rejection> + Copy

Creates a Server-sent Events filter.

The yielded Sse is used to reply with stream of events.

Note

This filter combines multiple filters internally, so you don't need them:

  • Method must be GET
  • Header connection must be keep-alive when it present.

If the filters are met, yields a Sse. Calling Sse::reply will return a reply with:

  • Status of 200 OK
  • Header content-type: text/event-stream
  • Header cache-control: no-cache.
