Struct NotificationOperator 

pub struct NotificationOperator { /* private fields */ }

Explicit schema administration for one Notification Plugin Instance.

Implementations

impl NotificationOperator

pub async fn setup( database_url: &str, ) -> Result<SetupOutcome, NotificationOperatorError>

pub async fn upgrade( database_url: &str, ) -> Result<UpgradeOutcome, NotificationOperatorError>

pub async fn adopt_legacy( database_url: &str, ) -> Result<LegacyAdoptionOutcome, NotificationOperatorError>

One-time, fail-closed adoption of the exact pre-Plugin Notification schema. This records migration 1 without rewriting any ledger rows or replaying the immutable legacy SQL against the owned schema. Adoption is a mandatory maintenance-window operation: all Notification writers and DDL actors must be stopped. It locks the shared legacy ledger in share mode and all legacy Notification tables in access-exclusive mode until the catalog proof and Plugin migration record commit. The advisory shared maintenance advisory lock coordinates cooperating schema operators, followed by the Notification-specific advisory lock. PostgreSQL has no schema namespace lock here, so these locks do not make arbitrary concurrent CREATE statements atomic with adoption.

pub async fn connect( database_url: &str, ) -> Result<Self, NotificationOperatorError>

pub fn schema(&self) -> &str
