Source§

fn can_create<'life0, 'life1, 'async_trait>( &'life0 self, entity: &'life1 E, ) -> Pin<Box<dyn Future<Output = PolicyDecision> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Can the entity be soft-deleted?
Source§

fn can_update<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, current: &'life1 E, updated: &'life2 E, ) -> Pin<Box<dyn Future<Output = PolicyDecision> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,
