Implementations

impl Theme

pub fn studio_dark() -> Self

pub fn studio_light() -> Self

pub fn from_tokens(tokens: &TokenDocument, density: Density) -> Self

Builds a theme from any validated token document at one density.

Density scales spacing, control geometry and type independently, and rounds to whole pixels so compact layouts stay on the pixel grid.

pub fn surface(&self, surface: Surface) -> Hsla

pub fn text_color(&self, tone: TextTone) -> Hsla

pub fn semantic_color(&self, color: SemanticColor) -> Hsla

pub fn space(&self, step: Space) -> f32

pub fn radius(&self, step: Radius) -> f32

pub fn type_style(&self, scale: TypeScale) -> TypeStyle

pub fn easing(&self, easing: MotionEasing) -> [f32; 4]

pub fn spring(&self, preset: SpringPreset) -> SpringTokens

pub fn shadow(&self, level: Elevation) -> &[BoxShadow]

pub fn layer(&self, layer: Layer) -> i32

pub fn install(cx: &mut App)

Installs the bundled theme registry. Idempotent.

pub fn get(cx: &App) -> &Self

pub fn focus_ring(&self) -> Vec<BoxShadow>

The ring drawn around whichever control currently has the keyboard.

It spreads outward in the focus colour, so it reads differently from Self::selected_ring: focus says where the next keystroke goes, selection says which answer is current, and a reader that cannot tell the two apart cannot tell what pressing a key would do.

pub fn selected_ring(&self) -> Vec<BoxShadow>

pub fn glow(&self, color: Hsla) -> Vec<BoxShadow>

The colour a surface in a named state bleeds into the pixels around it.

It is the state itself made visible at the edge, which is what lets a surface report “running” or “failed” without a border drawn round it. Blurred and unoffset, so nothing about it reads as a line.

Trait Implementations

impl Clone for Theme

fn clone(&self) -> Theme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Theme

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

Formats the value using the given formatter.

impl Default for Theme

fn default() -> Self

Returns the “default value” for a type.
