LGTM but I have questions

[jmg-duarte]

Nit: you can expose the SP/Market function that defines the value and query it here
Or at least leave a note for one of us shmucks that will do that

Added a note.

[jmg-duarte]

Why are you making a clone, inside a closure, that doesn't even care for the argument it takes?

[th7nder]

SectorStorage: Fn(SectorNumber) -> Option<ProvenSector> -> is the trait bound.
So basically it means that the closure must be callable multiple times. Without the clone, sector_storage ends up being FnOnce, so a smaller guarantee thatn the Fn.
