Struct Event 

#[non_exhaustive]
pub struct Event<'a> {
    pub kind: EventKind,
    pub id: RequestId,
    pub route: Option<&'a str>,
    pub status: u16,
    pub code: &'static str,
    pub source: Option<&'a (dyn Error + 'static)>,
}

One event.

use std::sync::{Arc, Mutex};
use web_net::{App, Event, Events, get};

#[derive(Default)]
struct Codes(Mutex<Vec<(u16, &'static str)>>);
impl Events for Codes {
    fn event(&self, e: &Event<'_>) {
        self.0.lock().unwrap().push((e.status, e.code));
    }
}

let codes = Arc::new(Codes::default());
let app = App::builder().events(Arc::clone(&codes)).route(get("/", |cx| cx.text(200, "hi"))).build()?;
serve_net::testing::respond(&app, b"GET /missing HTTP/1.1\r\nHost: localhost\r\n\r\n");
assert_eq!(*codes.0.lock().unwrap(), [(404, "route.none")]);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: EventKind

What happened.

id: RequestId

The request’s reference.

route: Option<&'a str>

The matched route’s pattern, if routing got that far.

status: u16

The status answered.

code: &'static str

A stable code ("url.encoded_slash", a gate’s code, a handler’s).

source: Option<&'a (dyn Error + 'static)>

The underlying error, for the logs only.

Trait Implementations

impl<'a> Debug for Event<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
