facet

The platform-neutral UI vocabulary and tree used by every facet backend.

Add it with cpc pm add . facet, which writes its dependency closure:

[dependencies]
facet = "*"

Then import the modules you use:

import "facet/facet" as facet;
import "facet/elements" as ui;

fn content() -> facet::Node {
    var column: facet::Builder = facet::Builder::new();
    column.add(ui::label("Hello", key: "greeting"));
    return ui::column(column, key: "content");
}

facet describes UI and owns its state; a backend such as facet_appkit, facet_gtk, facet_uikit, or facet_win32 mounts the tree.
