pub const POLL_BACKOFF: Duration;Expand description
How long to wait after a failed request before retrying. We
intentionally do not escalate backoff here: if the engine is
down, the status bar already shows engine:DOWN via the WS
subscriber, and the operator-state segment degrading to ops:?
after 30 s is the honest rendering (see
OPERATOR_STATE_STALE_AFTER in the widget).
