Struct Wiring 

pub struct Wiring {
    pub config: Arc<Config>,
    pub graph: Arc<RouteGraph>,
    pub hangars: PathBuf,
    pub logbook: PathBuf,
    pub queue: QueueFlight,
    pub book: BookLayover,
    pub read_learnings: ReadLearnings,
    pub write_learnings: WriteLearnings,
}

Where a runtime reads and writes everything outside itself.

A struct rather than six positional arguments: they are all closures or paths, so the compiler would not catch two of them being swapped, and swapping the queue for the layover shelf is the kind of mistake that only shows up in production.
