Struct WorkerService 

pub struct WorkerService<Q, S, E, F>
where
    Q: JobQueue,
    S: DatasetStore,
    E: EmbeddingProvider,
    F: PortalClientFactory,
{ /* private fields */ }

Worker service that processes jobs from the queue.

This service polls for pending jobs and processes them using the HarvestService. It supports graceful shutdown via cancellation tokens.

Implementations

impl<Q, S, E, F> WorkerService<Q, S, E, F>

where Q: JobQueue, S: DatasetStore, E: EmbeddingProvider, F: PortalClientFactory,

pub fn new( queue: Q, harvest_service: HarvestService<S, E, F>, config: WorkerConfig, ) -> Self

Create a new worker service.

pub async fn run<WR, HR>( &self, cancel_token: CancellationToken, worker_reporter: &WR, harvest_reporter: &HR, ) -> Result<(), AppError>

where WR: WorkerReporter, HR: ProgressReporter,

Run the worker until cancelled.

The worker will:

1. Poll for available jobs
2. Claim and process jobs
3. Handle retries on failure
4. Release jobs on graceful shutdown

pub async fn process_single_job<WR, HR>( &self, job_id: Uuid, cancel_token: CancellationToken, worker_reporter: &WR, harvest_reporter: &HR, ) -> Result<(), AppError>

where WR: WorkerReporter, HR: ProgressReporter,

Process a single job by ID (for one-off execution, e.g., CLI).

This method is useful for processing a specific job without running the full polling loop.
