Expand description

Trait for storing push notification configurations.

Object-safe; used as Box<dyn PushConfigStore>.

Required Methods§

Source

fn set<'a>( &'a self, config: TaskPushNotificationConfig, ) -> Pin<Box<dyn Future<Output = A2aResult<TaskPushNotificationConfig>> + Send + 'a>>

Stores (creates or updates) a push notification config.

§Errors

Returns an A2aError if the operation fails.

Source

fn get<'a>( &'a self, task_id: &'a str, id: &'a str, ) -> Pin<Box<dyn Future<Output = A2aResult<Option<TaskPushNotificationConfig>>> + Send + 'a>>

Retrieves a push notification config by task ID and config ID.

§Errors

Returns an A2aError if the operation fails.

Source

fn list<'a>( &'a self, task_id: &'a str, ) -> Pin<Box<dyn Future<Output = A2aResult<Vec<TaskPushNotificationConfig>>> + Send + 'a>>

Lists all push notification configs for a task.

§Errors

Returns an A2aError if the operation fails.

Source

fn delete<'a>( &'a self, task_id: &'a str, id: &'a str, ) -> Pin<Box<dyn Future<Output = A2aResult<()>> + Send + 'a>>

Deletes a push notification config by task ID and config ID.

§Errors

Returns an A2aError if the operation fails.

Provided Methods§

Source

fn count( &self, ) -> Pin<Box<dyn Future<Output = A2aResult<Option<usize>>> + Send + '_>>

Returns the total number of stored configs the handler should count against its global ceiling, or None if this backend does not report a count (in which case only the per-task cap is enforced).

Implementations that can answer cheaply (an in-memory size, a SQL COUNT(*)) return Some(n) so the handler can bound total growth uniformly — without it, configs spread across unboundedly many task ids grow a SQL-backed store without limit. Tenant-scoped stores report the count for the current tenant, yielding a per-tenant ceiling.

The default returns None so existing custom implementations keep compiling and behave exactly as before.

§Errors

Returns an A2aError if the operation fails.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
