Enum DarkPolicy 

pub enum DarkPolicy {
    Auto,
    LightOnly,
    Explicit {
        accent: Color,
    },
}

How the emitted tokens.css should handle dark mode.

The generated file is appended after the framework’s baked CSS bundle, so a :root-only override (light values, no dark blocks) ties the framework’s [data-theme="dark"] on specificity and wins by source order — leaking light surfaces into dark mode. To avoid that, emit always writes the dual dark structure the framework uses: an explicit :root[data-theme="dark"] block (higher specificity, tie-breaks the toggle) and a @media (prefers-color-scheme: dark) { :root { … } } auto block (later source order than the plain :root, so OS-dark without an explicit toggle is covered too). This enum decides what values those dark blocks carry.

Variants

Auto

Auto-derive dark from the resolved light tokens: a brand-agnostic slate ladder (inverted surfaces, slate text) with the brand accent lifted until it clears AA_TEXT on the dark surface. The default.

LightOnly

The brand is light-only. Dark pins to the framework’s default dark palette (slate surfaces + the framework’s lifted teal accent) — a neutral dark override, never light values. Use this to opt out of brand color in dark rather than leak light.

Explicit

Explicit dark accent supplied by the brand author; the dark blocks lift it for AA_TEXT on the dark surface. Surfaces and text stay on the framework slate ladder (brand-agnostic, exactly as the light :root block keeps the chrome ladder brand-agnostic).

Fields

accent: Color

The author’s chosen dark-mode accent (pre-lift).

Trait Implementations

impl Clone for DarkPolicy

fn clone(&self) -> DarkPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DarkPolicy

impl Debug for DarkPolicy

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

Formats the value using the given formatter.

impl Default for DarkPolicy

fn default() -> DarkPolicy

Returns the “default value” for a type.

impl PartialEq for DarkPolicy

fn eq(&self, other: &DarkPolicy) -> 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.
