Struct Theme 

pub struct Theme {
    pub colors: HashMap<&'static str, Color>,
    pub radii: HashMap<&'static str, f32>,
    /* private fields */
}

The values that theme tokens resolve against.

The maps are keyed by the token names, so an application can add its own tokens by inserting under names of its own. Built-in themes come from Theme::light and Theme::dark.

Fields

colors: HashMap<&'static str, Color>

The colors, keyed by ColorToken name.

radii: HashMap<&'static str, f32>

The corner radii in logical pixels, keyed by RadiusToken name.

Implementations

impl Theme

pub fn light() -> Theme

A light theme that defines every built-in token.

use smudge_core::theme::{ColorToken, Theme};

let theme = Theme::light();
let surface = theme.color(ColorToken::SURFACE);
assert!(surface.is_opaque());

pub fn dark() -> Theme

A dark theme that defines every built-in token.

pub fn color(&self, token: ColorToken) -> Color

Returns the color token resolves to.

Panics

Panics in debug builds when the theme does not define the token. A release build falls back to magenta, which shows the mistake on screen.

pub fn radius(&self, token: RadiusToken) -> f32

Returns the radius in logical pixels that token resolves to.

Panics

Panics in debug builds when the theme does not define the token. A release build falls back to zero, which gives square corners.

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 PartialEq for Theme

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

Equality operator ==.

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

Inequality operator !=.
