Type Alias CompactionHook 

pub type CompactionHook = Arc<dyn Fn(CompactedContext) -> Pin<Box<dyn Future<Output = Result<()>> + Send>> + Send + Sync>;

Async hook invoked after context compaction completes.

Receives the CompactedContext and returns a Result<()> future. The future is awaited within the agent loop, so async operations (memory storage, logging, etc.) are safe here.

Example

let config = AgentLoopConfig {
    on_compaction: Some(Arc::new(|ctx: CompactedContext| {
        let summary = ctx.summary.clone();
        Box::pin(async move {
            memory_store.save(summary).await
        })
    })),
    ..Default::default()
};

Aliased Type
