Struct Elevation 

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

Elevation, by the design language’s one rule: only floating things cast a shadow. Window tiles, bars, cards and selected controls have none — a tile is separated by the ground and its window edge, a selection is a lift (crate::tokens::Intents::selection).

Fields

floating: Shadow

The one shadow a floating thing casts — a menu, popover, the palette, a sheet, quick settings, a toast, a tooltip, a dragged object: soft and wide, so it reads as distance rather than as an outline. Paint it with crate::surface::shadow at the surface’s own radius.

floating_edge: AlphaColor<Srgb>

The 1 px inner light edge a floating surface draws on a dark material, just inside its outline. Transparent on a light material.

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

Elevation on a dark material.

pub fn light() -> Elevation

Elevation on a light material — the same geometry, softened by LIGHT_SHADOW_SCALE, with no inner edge.

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
