Nodes

Module node

Tagged nodes making up a rendered view.

import ui.flow.node

A view renders into a tree of nodes. Node is the shared shape — a name plus children — and each concrete node carries a @Tag naming the element the host draws. Colors are accepted as ColorLike, so a hex Int, an RGB array or a Color all work.

attr Node {
	name: String
	children(self) -> [@Node]
}

An element in the rendered tree. name identifies the element, children yields the nodes below it, so a host walks the tree without knowing the concrete types.
