Struct TracingMiddleware 

pub struct TracingMiddleware;

Built-in middleware that wraps each job execution in a tracing span carrying job.id, job.method, job.queue, and job.attempt.

Installed implicitly by JobProcessor as the outermost layer so every worker execution gets a structured span for free. Users can opt out by constructing their middleware stack manually (the processor’s implicit install is a convenience, not a requirement).
