Struct AdminTheme 

pub struct AdminTheme {
    pub accent: String,
    pub bg: String,
    pub surface: String,
    pub text: String,
    pub text_muted: String,
    pub border: String,
}

1.8.2 — full admin chrome palette. Each field maps onto one of the framework’s --rio-* design tokens defined in admin/base.html, so overriding these values via Admin::theme(...) re-skins the entire admin shell (topbar, sidebar, body, cards, headings, hairlines) without touching CSS or rebuilding Tailwind.

Defaults match the framework’s current chrome so a project that doesn’t call .theme(...) renders unchanged. Operators typically override 1–3 fields and let the rest default:

admin.theme(AdminTheme {
    accent:  "#1e6ba8".into(),
    topbar:  "#1e3a5f".into(),
    bg:      "#f0f5fa".into(),
    ..AdminTheme::default()
})

Hex form (#rrggbb or rrggbb); leading # is auto-normalised at render time. Malformed values fall back to framework defaults rather than panic — the admin path never breaks over a config typo.

Fields

accent: String

Primary brand colour. Drives --rio-accent (logo mark, focus rings, primary buttons, badges) AND the --ds-color-accent CSS variable (for Tailwind utilities that bake the accent with opacity, like bg-accent/10).

bg: String

Page background. Drives --rio-bg — the canvas behind the shell on every admin page.

surface: String

Card / topbar / sidebar surface. Drives --rio-bg-surface-1 — the colour of the topbar background and any elevated surface.

text: String

Body text colour. Drives --rio-text — body copy AND the “skip-to-content” link AND the topbar brand title.

text_muted: String

Secondary / supporting text. Drives --rio-text-muted — the “signed in as …” line, table hints, and most metadata labels.

border: String

Border / hairline colour. Drives --rio-border — every visible hairline on cards, the topbar bottom-border, and table dividers.

Trait Implementations

impl Clone for AdminTheme

fn clone(&self) -> AdminTheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdminTheme

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

Formats the value using the given formatter.

impl Default for AdminTheme

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for AdminTheme

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