Expand description

Receiver of per-tool-round checkpoints.

The framework ships one adapter: SessionStoreCheckpointSink which forwards to a crate::store::SessionStore. Hosts can implement custom sinks (e.g. push directly to Redis) by implementing this trait.

Required Methods§

Source

fn save_checkpoint<'life0, 'life1, 'async_trait>( &'life0 self, checkpoint: &'life1 LoopCheckpoint, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Persist a checkpoint. Called from inside the agent loop after a successful tool round. Errors are logged at warn level and otherwise swallowed — losing a checkpoint must not halt the live run.

Source

fn load_latest<'life0, 'life1, 'async_trait>( &'life0 self, run_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Option<LoopCheckpoint>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Load the latest checkpoint for run_id, if any. Returns None when no checkpoint has been recorded.

Dyn Compatibility§

This trait is dyn compatible.

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