Required Methods§

Source

fn get_dependents<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, CacheError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Get keys that depend on the given key

If key A depends on key B, then get_dependents("B") should return ["A"].
