Enum SessionId 

pub enum SessionId {
    Initial(Uuid),
    Clone {
        old: Uuid,
        new: Uuid,
    },
    Drop(Uuid),
}

Variants

Initial(Uuid)

A new session was opened.

Clone

A session was cloned; new starts as a copy of old.

Fields

old: Uuid

The session being copied.

new: Uuid

The session receiving the copy.

Drop(Uuid)

A session was dropped and its state can be released.
