Struct Theme 

pub struct Theme {
    pub id: ThemeId,
    pub appearance: ThemeAppearance,
    pub colors: ColorTokens,
    pub layout: LayoutTokens,
    pub typography: TypographyTokens,
    pub shape: ShapeTokens,
    pub motion: MotionTokens,
    pub style_slots: ComponentStyleSlots,
    pub extensions: ThemeExtensions,
}

Fields

id: ThemeId

Stable identity of this theme — see ThemeId. Serde-defaulted so older serialized themes (which predate the field) still deserialize.

appearance: ThemeAppearance

colors: ColorTokens

layout: LayoutTokens

typography: TypographyTokens

shape: ShapeTokens

motion: MotionTokens

style_slots: ComponentStyleSlots

Typed Rc<dyn FooStyle> slot bag for theme-wide style installations. None per slot means “use the widget’s local Recipe*Style default”; apps install per-theme overrides via theme.style_slots.button = Some(Rc::new(MyButton)). Per-call .style(...) on a widget always wins over the slot.

extensions: ThemeExtensions

Implementations

impl Theme

pub fn new( appearance: ThemeAppearance, colors: ColorTokens, layout: LayoutTokens, typography: TypographyTokens, shape: ShapeTokens, motion: MotionTokens, ) -> Self

Build a Theme from raw token data. Most apps go through a preset constructor (e.g. teksilo_core::presets::intui::light) rather than calling this directly — presets aggregate the matching Recipe*Style defaults under the same call.

pub fn with_id(self, id: impl Into<Cow<'static, str>>) -> Self

Set this theme’s ThemeId and return self for chaining. Used by preset constructors and apps building custom themes.

pub fn is_dark(&self) -> bool

Whether this theme paints on a dark background. Convenience for theme.appearance.is_dark().

pub fn for_inactive_window(&self) -> Theme

A copy of this theme projected for an inactive window — the accent family and focus indicators desaturated toward graphite (see ColorTokens::for_inactive_window). The paint walker swaps this in when the host window loses focus, so every accent-coloured control greys out with no per-widget code. Only the colours change; typography / layout / shape / motion are untouched, so this never affects layout.

pub fn for_high_contrast(&self) -> Theme

Project into a high-contrast variant (WCAG 1.4.6 Enhanced / EN 301 549 §11.7), applied at paint time when the OS “increase contrast” preference is set. See ColorTokens::for_high_contrast.

pub fn extension<T: Any + Send + Sync>(&self) -> Option<&T>

Look up a typed theme extension. See ThemeExtensions.

pub fn with_extension<T: Any + Send + Sync>(self, value: T) -> Self

Attach a typed extension and return self for chaining. See ThemeExtensions.
