Enum LoginCheck 

pub enum LoginCheck {
    Command(Vec<String>),
    Unavailable(String),
}

How the runtime asks the harness whether it is signed in for this user, without spending a turn.

Variants

Command(Vec<String>)

Run description.binary with these arguments, the way the version check runs it, and hand what it printed to read-login. Never empty: a driver naming no arguments is refused at load, since the bare binary may start a session.

Unavailable(String)

The harness offers no way to ask without a turn; the reason, shown to the person cut to its first line and 200 characters.
