Struct Broadcaster 

pub struct Broadcaster { /* private fields */ }

Fans change events out to every subscriber.

A build reports what it produced through this, so a caller — a watch loop, a dev server wanting to reload a browser — can react without polling the output directory itself. Subscribers whose channel has closed are dropped on the next broadcast.
