Import
import { LayoutParams } from "@typed/router/Matcher";Signatures
export type LayoutParams<Params, A, E, R> = {
readonly params: RefSubject.RefSubject<Params>;
readonly content: Fx.Fx<A, E, R>;
};Why
Parameter-only route updates can reach a retained layout without remounting its content.
Ownership and lifetime
The executor owns both RefSubjects for the active layout child Scope. Reading them does not transfer ownership; retaining them beyond that Scope observes finalized state.
Property: content
Reactive output nested immediately inside this layout.
Property: content: Why
A retained outer layout can observe replacement of an inner layout or route handler.
Property: content: Ownership and lifetime
The layout manager owns the backing content RefSubject in the same child Scope. Inner layouts are acquired first, so this Fx represents the already-wrapped inner subtree.
Property: params
Reactive decoded parameters for the currently selected route.
Property: params: Why
Parameter-only navigation updates a retained layout without reconstructing it.
Property: params: Ownership and lifetime
The layout manager owns this RefSubject in the layout’s child Scope and updates it before the retained layout renders the next value.
