Enum Progress 

#[non_exhaustive]
pub enum Progress {
    Idle,
    Head,
    Body,
    AwaitingResponse,
    WritingBody,
    Upgraded,
    Closed,
}

The phase of a connection, for drivers that run header-read, request, and response deadlines: what ServerConn::progress and ClientConn::progress report.

Examples

use http_net::{Progress, ServerConn, ServerEvent};

let mut conn = ServerConn::new();
assert_eq!(conn.progress(), Progress::Idle);
let _ = conn.feed(b"GET / HTTP/1.1\r\n");
assert!(matches!(conn.poll(), Ok(ServerEvent::NeedInput)));
assert_eq!(conn.progress(), Progress::Head);

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.

Idle

Between messages: no byte of the next one has been seen. Idle keep-alive time belongs to this phase, so a request deadline should not start here.

Head

Some bytes of a head have arrived; the head is not complete.

Body

The head is complete and body bytes are still to come.

AwaitingResponse

Server: the request is complete (or has no body left to read), or it was refused with a parse error, and its response is not finished. Client: the request was sent and nothing of the response has arrived, or a pipelined request is next.

WritingBody

A streamed body is being written: the response on a server, the request on a client.

Upgraded

The connection belongs to another protocol.

Closed

The connection is finished (or will be once the last response is written).
