Struct AgentBlockWorker 

pub struct AgentBlockWorker {
    pub handler: WorkerJoinHandler,
}

Concrete Worker type for the AgentBlock kind — the handle for an LLM call routed through the agent-block-core SDK. Embeds a WorkerJoinHandler to carry the async signal. The intent is to eventually keep the SDK-specific quirks — the agent_result event name, payload shape, shutdown-token bridging, agent_result.content normalisation — contained inside this struct. Today it lands as a thin shape holding only the async signal; Phase B adds the normalisation layer here and structurally eliminates the token-boilerplate waste observed in observation #2.

Fields

handler: WorkerJoinHandler

The completion-signal handle for this agent-block SDK call’s spawned task.

Trait Implementations

impl From<WorkerJoinHandler> for AgentBlockWorker

fn from(handler: WorkerJoinHandler) -> Self

Converts to this type from the input type.

impl Worker for AgentBlockWorker

fn id(&self) -> &WorkerId

This worker’s identity — used for logging and to tie cancellation back to the right worker.

fn cancel_token(&self) -> CancellationToken

Token that carries the cancel signal. Clonable — this is the path the engine uses to cancel from the outside.

fn join<'async_trait>( self: Box<Self>, ) -> Pin<Box<dyn Future<Output = Result<(), WorkerError>> + Send + 'async_trait>>

where Self: 'async_trait,

Await the completion signal. The worker is consumed — one worker, one join. Ok(()) means the worker ran to completion; Err means it was cancelled, failed, or panicked internally. Values do not come back through this trait; use engine.output_tail for those.
