Enum ThemeColor 

pub enum ThemeColor {
    Light(String),
    Dark(String),
    LightDark {
        light: String,
        dark: String,
    },
}

The colour a browser tints its chrome with, and the schemes the site supports.

The two are one type because they must agree: declaring color-scheme: light dark while offering a single theme colour gives a dark page a light address bar, and declaring color-scheme: light on a site with dark styles renders its form controls and scrollbars wrong. Naming the scheme in the constructor makes the contradiction unrepresentable.

Variants

Light(String)

A light-only site.

Dark(String)

A dark-only site.

LightDark

A site that follows the reader’s preference.

Fields

light: String

dark: String

Implementations

impl ThemeColor

pub fn light(color: impl Into<String>) -> Self

A light-only site.

pub fn dark(color: impl Into<String>) -> Self

A dark-only site.

pub fn light_dark(light: impl Into<String>, dark: impl Into<String>) -> Self

A site that follows prefers-color-scheme.

Both colours should be the page’s background per scheme, so the browser chrome reads as continuous with the page rather than as an accent stripe above it.

pub const fn color_scheme(&self) -> &'static str

The <meta name="color-scheme"> value.

pub fn primary(&self) -> &str

One representative colour, for contexts that accept only a single value — the web app manifest, which has no media-query equivalent. The light value wins, matching how a browser renders a splash screen by default.

pub fn tags(&self) -> Vec<ThemeColorTag>

The <meta name="theme-color"> tags to emit, in order.
