Struct MiddlewareWorker 

pub struct MiddlewareWorker {
    pub handler: WorkerJoinHandler,
}

Generic Worker used only on the middleware (wrap_join) wrap path, so kind-agnostic post-processing wrap results can be returned as Box<dyn Worker>. Unlike a per-kind Worker, this does not represent “a specific kind’s execution” — it is a thin wrapper that layers a post-processor on top of an existing Worker.

Named after its role: the “Worker for the middleware path” — the type boxed as the return value by wrap_join consumers (Audit / MainAI / Senior / LongHold / Lua after-hook, and so on).

Fields

handler: WorkerJoinHandler

The wrapped completion handle; join delegates to this.

Trait Implementations

impl From<WorkerJoinHandler> for MiddlewareWorker

fn from(handler: WorkerJoinHandler) -> Self

Converts to this type from the input type.

impl Worker for MiddlewareWorker

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.
