Struct PgNotifyIntentSource

Source

pub struct PgNotifyIntentSource { /* private fields */ }

Expand description

Thin sqlx PgListener wrapper for invalidation wake-ups.

The source intentionally does not apply invalidation by itself. It lets a worker wake up and drain the durable outbox sooner; missed notifications are recovered by the normal polling path.

Implementations§
