Struct Elevation 

pub struct Elevation {
    pub window: Shadow,
    pub floating: Shadow,
    pub contact: Shadow,
    pub floating_edge: AlphaColor<Srgb>,
    pub glass_inner: Shadow,
    pub glass_outer: Shadow,
    pub shadow_scale: f32,
}

Elevation (docs/design-language.md, “Surfaces”): a window tile casts one soft shadow that lifts it off the desktop ground; a floating thing casts two, a tight contact layer that defines its edge and a wide one that reads as distance. Bars, cards and selected controls cast none: a selection is a lift (crate::tokens::Intents::selection).

Fields

window: Shadow

The soft shadow under a window tile on the desktop ground, painted at the tile’s radius.

floating: Shadow

The wide layer of a floating thing’s shadow — a menu, popover, the palette, a sheet, quick settings, a toast, a tooltip, a dragged object. Paint both layers with crate::surface::floating_shadow.

contact: Shadow

The tight layer at a floating surface’s foot, under the wide one: it defines the edge where the wide shadow alone reads as haze.

floating_edge: AlphaColor<Srgb>

The 1 px inner hairline a floating surface draws just inside its outline: white on a dark material, black on a light one.

glass_inner: Shadow

The wheel disc’s rim light: a different vocabulary from a drop shadow, of which only the hue is read.

glass_outer: Shadow

The wheel disc’s outer bloom. Only the hue is read.

shadow_scale: f32

The factor this material’s shadow was scaled by relative to the dark one, for a widget composing its own soft stack (a sprite, a ring).

Implementations

impl Elevation

pub fn dark() -> Elevation

pub fn light() -> Elevation

Elevation on a light material: the same geometry, lighter, and a black inner hairline.

impl Elevation

pub fn with_depth(self, depth: Depth, outline: Outline) -> Elevation

This elevation under a theme’s depth: shadows at strength; for an outline, no shadows and the window’s and a floating thing’s outline in outline; for none, nothing at all. The glass rim and bloom are the wheel’s own vocabulary and stay.

Trait Implementations

impl Clone for Elevation

fn clone(&self) -> Elevation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Elevation

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Elevation

fn default() -> Elevation

Returns the “default value” for a type.

impl PartialEq for Elevation

fn eq(&self, other: &Elevation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Elevation

impl StructuralPartialEq for Elevation
