Interface ReceiverLayer<O, S>

One layer around a tree's outermost call, closest first: what it sets.

interface ReceiverLayer<O = unknown, S = unknown> {
    journal?: JournalChoice<S> | null;
    observers?: readonly O[];
    programObservers?: boolean;
    where: "own" | "block" | "configure";
}

Properties

journal?: JournalChoice<S> | null

Absent: the layer sets none; null: it sets "no journal".

observers?: readonly O[]

programObservers?: boolean

A host layer's false: the observers of the program's own settings are given nothing (it only removes).
