Struct TenantAwarePostgresTaskStore 

pub struct TenantAwarePostgresTaskStore { /* private fields */ }

Tenant-scoped PostgreSQL-backed TaskStore.

Each operation is scoped to the tenant from TenantContext. Tasks are stored with a tenant_id column for database-level isolation, enabling efficient per-tenant queries and deletion.

Errors

Returns an error if the database cannot be opened or migration fails.

pub async fn from_pool(pool: PgPool) -> Result<Self, Error>
