llimphi-layer

Runs a Llimphi App as a wlr-layer-shell surface (a bar anchored to an edge) rather than as a window.

It lets an app sit at the level of eww/waybar on any wlroots compositor (mirada, Hyprland, Sway, river…): it anchors to an edge, declares an optional exclusive zone — the compositor reserves the strip and tiles the rest — and paints itself reusing Llimphi's pipeline (mount → compute → paint → render).

It is the smithay-client-toolkit + wgpu plumbing that pata proved in production, extracted into a generic runner over the App trait. Unlike pata (N surfaces + tray/dock/sidebar/…), this runs one surface and no domain logic: the app provides view/update/on_key and this crate lends it the edge. Useful, for instance, to dock shuma as a bar.

struct MyBar;
impl llimphi_ui::App for MyBar { /* … */ }
llimphi_layer::run::<MyBar>(llimphi_layer::LayerConfig {
    edge: llimphi_layer::Edge::Bottom,
    thickness: 40,
    keyboard: llimphi_layer::Keyboard::OnDemand,
    ..Default::default()
})?;
