Struct SqliteScannerHandle 

pub struct SqliteScannerHandle { /* private fields */ }

Spawned scanner supervisor. Holding this handle keeps the reconciler tasks alive; drop-on-backend or explicit shutdown drains them. Returned by [spawn_scanners]; stored inside SqliteBackendInner so EngineBackend::shutdown_prepare can drain on server shutdown.

Implementations

impl SqliteScannerHandle

pub async fn shutdown(&self, grace: Duration) -> usize

Signal shutdown and await drain up to grace. Returns the number of tasks that did not exit cleanly within the grace window (for operator logging). Subsequent calls are no-ops.

Trait Implementations

impl Drop for SqliteScannerHandle

fn drop(&mut self)

Best-effort signal on drop. Tasks exit at their next tick; if the caller wants a bounded drain they must call Self::shutdown explicitly (per PG parity).
