Trait for response storage

Required Methods§

Source

fn store_response<'life0, 'async_trait>( &'life0 self, response: StoredResponse, ) -> Pin<Box<dyn Future<Output = Result<ResponseId, ResponseStorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Store a new response

Source

fn get_response<'life0, 'life1, 'async_trait>( &'life0 self, response_id: &'life1 ResponseId, ) -> Pin<Box<dyn Future<Output = Result<Option<StoredResponse>, ResponseStorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get a response by ID

Source

fn delete_response<'life0, 'life1, 'async_trait>( &'life0 self, response_id: &'life1 ResponseId, ) -> Pin<Box<dyn Future<Output = Result<(), ResponseStorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete a response

Source

fn list_identifier_responses<'life0, 'life1, 'async_trait>( &'life0 self, identifier: &'life1 str, limit: Option<usize>, ) -> Pin<Box<dyn Future<Output = Result<Vec<StoredResponse>, ResponseStorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

List recent responses for a safety identifier

Source

fn delete_identifier_responses<'life0, 'life1, 'async_trait>( &'life0 self, identifier: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<usize, ResponseStorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete all responses for a safety identifier

Provided Methods§

Source

fn get_response_chain<'life0, 'life1, 'async_trait>( &'life0 self, response_id: &'life1 ResponseId, max_depth: Option<usize>, ) -> Pin<Box<dyn Future<Output = Result<ResponseChain, ResponseStorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get the chain of responses leading to a given response.

Walks previous_response_id links from the given response backwards, collecting up to max_depth responses (or unlimited if None). Returns responses in chronological order (oldest first).

The default implementation calls self.get_response() in a loop with cycle detection to prevent infinite loops from self-referencing chains. Backends that can walk the chain more efficiently (e.g. with a single lock or a recursive SQL query) should override this.
