Struct Drawer 

pub struct Drawer { /* private fields */ }

A slide-in side panel. Attach to any widget’s paint via .drawer(open, ..) (see DrawerApi) or use directly: when open, it pushes a dimmed scrim + a left-anchored panel overlay. Tapping the scrim closes it.

Customization (D115/Phase 32 Step 1): Drawer::full_screen makes the panel cover the whole window (mobile nav-page style); Drawer::background and Drawer::scrim_color replace the theme-derived defaults.

Implementations

impl Drawer

pub fn new( open: Atom<bool>, panel: impl Fn() -> BoxedWidget + Send + Sync + 'static, ) -> Self

pub fn width(self, w: f32) -> Self

pub fn full_screen(self) -> Self

Cover the entire window instead of a fixed-width side panel — the full-screen navigation-page presentation. There is no scrim area left to tap, so dismissal is the panel content’s job (or Escape).

pub fn background(self, c: Color) -> Self

Panel fill — defaults to the theme’s surface.

pub fn scrim_color(self, c: Color) -> Self

Scrim (barrier) color over the content behind the panel — defaults to black at ~47% opacity.

pub fn material(self, m: ShaderMaterial) -> Self

Per-instance shader material — replaces the panel fill when resolved. Beats the theme’s DrawerMaterial default (D124 Step 5).

pub fn emit(&self)

Emit the drawer overlay if open. Call from a host widget’s paint (the Scaffold does this) — the drawer has no visual of its own when closed.
