pub fn screen_control_offered(socket_path: &str) -> Result<bool, String>Expand description
Whether the compositor on socket_path serves zkde_screencast_unstable_v1 at the

offered a second display on. A registry read alone, so a session is asked on every
landing without a screen coming or going on it; whether a grown screen registers is
[grow]’s to prove. Err only when the compositor is unreachable.
