pub enum QueryState {
Ready,
Running,
Paused,
Stopped,
}Expand description
Lifecycle state of a StreamingQuery (requires jit feature).
Variants§
Ready
Query is built but not yet started.
Running
Query is actively processing events.
Paused
Query is temporarily paused (can be resumed).
Stopped
Query has been stopped (terminal state).
