Connection.Session

Connection owns terminal control-mode transport to the exact daemon that materialized its session. Values obtained from Server or Session retain the connection. Closing is terminal: they neither reconnect nor fall back to a subprocess. Its lanes are attached tmux clients; closing the last client can trigger tmux's destroy-unattached or exit-unattached policy. Destroying its initial session moves the clients to another session when one exists; the retained Session value keeps its original identity.

Session is one materialized tmux session record. It is normally returned by Server.Snapshot, Server.Session, or Session.Refresh. A zero Session is not a usable tmux target.
