I have a tree like structure: Warehouse <- Zone<'p>.

#[derive(Debug, Clone, Dummy)]
pub struct WarehouseTopology {
    pub label: String,
}

#[derive(Debug, Clone, Dummy)]
pub struct ZoneTopology<'p> {
    pub _whs: &'p WarehouseTopology,
    pub label: String,
}

Why can't I derive Dummy for it?

Well, I was able to split the struct onto a fakeable part and non-fakeable (keeping a reference).

#[derive(Serialize)]
pub struct ZoneTopology {
    _whs: &'p Parent,
   #[serde(flatten)]
   zone: Zone,
}

#[derive(Serialize, Dummy)]
pub struct Zone {
  label: String,
}

But macros could return something that accepts an argument — the reference to Parent.

let whs = Warehouse { .. };
let zone = faker.fake(&whs);
