pub fn watch(port: u16, target: WatchTarget, interval_ms: u64) -> Result<()>Expand description
concinnity debug watch <target>: poll a read-only snapshot every
interval_ms and print each reply until Ctrl-C. A connection failure on the
very first poll is fatal (exit 3) – there is nothing to watch; later
failures are printed and retried, so a server restart mid-session recovers.
