How do I set StatusCode in SSE handlers?

[infalmo]

Route sse/comments/:post should return status code 404 if the post is not found. Is this doable?

With a tuple like shown here.

Cool, never thought about that. Maybe the documentation can be updated to:

use axum::{
    http::StatusCode,
    Router,
    routing::get,
    response::{
        sse::{Event, KeepAlive, Sse},
        IntoResponse,
    },
};
use std::{time::Duration, convert::Infallible};
use futures::stream;

let app = Router::new().route("/sse", get(sse_handler));

async fn sse_handler() -> impl IntoResponse {
    // A `Stream` that repeats an event every second
    let stream = stream::repeat_with(|| Event::default().data("hi!"))
        .map(Ok)
        .throttle(Duration::from_secs(1));

    (StatusCode::OK, Sse::new(stream).keep_alive(KeepAlive::default()))
}

Hm it is kinda already shown just not specifically with SSE.
