Enum Accepted 

pub enum Accepted {
    Conn(Conn),
    Rejected(String),
    Unidentified(PeerRefusal),
    Vanished,
}

Outcome of Listener::accept: an authenticated connection, a rejected peer, or one that left before it could be identified.

Variants

Conn(Conn)

The peer was authenticated as the current user.

Rejected(String)

The peer failed OS-level authentication and was closed unread. The reason is the typed peer error, content-free.

Unidentified(PeerRefusal)

The peer could not be identified although its process exists, for example a client at a higher integrity level than this host (Windows). Closed unread. Carries the pid, the image path and a stable kind so the host can name the program (rightkit#1287).

Vanished

The peer left before it could be identified (a probe, or the shutdown wake-up). Closed; not worth a rejection event.
