Enum ClientEvent 

#[non_exhaustive]
pub enum ClientEvent<'a> {
    Response(ResponseHead<'a>),
    Body(&'a [u8]),
    ResponseEnd,
    NeedInput,
    Idle,
    Upgraded,
    Closed,
}

What a ClientConn has for the caller after poll.

Examples

use http_net::{ClientConn, ClientEvent, Request};

let mut conn = ClientConn::new();
let mut out = Vec::new();
conn.send_request(&Request::get("/").header("host", "example.com"), &mut out).unwrap();
let _ = conn.feed(b"HTTP/1.1 200 OK\r\nTransfer-Encoding: chunked\r\n\r\n3\r\nabc\r\n0\r\n\r\n");
let mut body = Vec::new();
loop {
    match conn.poll().unwrap() {
        ClientEvent::Response(resp) => assert_eq!(resp.status(), 200),
        ClientEvent::Body(chunk) => body.extend_from_slice(chunk),
        ClientEvent::ResponseEnd => break,
        other => panic!("{other:?}"),
    }
}
assert_eq!(body, b"abc");

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Response(ResponseHead<'a>)

The response head arrived (interim 1xx responses other than 101 are skipped; together they count against Limits::max_header_bytes). Its body follows as Body events, then ResponseEnd.

Body(&'a [u8])

A run of body bytes, after chunked decoding.

ResponseEnd

The response is complete.

NeedInput

More input is needed (or, for a body that runs until close, feed_eof once the server closes).

Idle

No request is outstanding; send the next one.

Upgraded

The server switched protocols (101 to an upgrade request, or 2xx to CONNECT); the response head was reported just before. Bytes of the new protocol that already arrived are in remaining_input.

Closed

The connection cannot carry another request: close the socket.
