Struct AdminTheme 

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

Project-level override patch for the admin chrome palette.

admin.css is the single source of truth for the framework’s design tokens (palette, semantic surfaces, typography scale, …). AdminTheme is purely a patch layer: every field is Option<String> and defaults to None, meaning “don’t override — let the stylesheet decide.” Out of the box the framework emits no inline <style> block at all.

Set a field — usually via the fluent builder methods or Admin::accent_color — to inject a --rio-* custom-property override on every page. Overrides are emitted as a single html { ... } block after admin.css, so they win cascade ties without !important. The framework is light-only.

Values are hex (#rrggbb or rrggbb); the leading # is auto-normalised at construction. Malformed input is rejected at override time rather than panicking — the admin path never breaks over a config typo.

Fields

accent: Option<String>

bg: Option<String>

surface: Option<String>

text: Option<String>

text_muted: Option<String>

border: Option<String>

Implementations

impl AdminTheme

pub fn new() -> Self

New empty patch — no overrides emitted, admin.css wins.

pub fn accent(self, color: impl Into<String>) -> Self

Override --rio-accent. Hex form, # optional.

pub fn bg(self, color: impl Into<String>) -> Self

Override --rio-bg (page canvas).

pub fn surface(self, color: impl Into<String>) -> Self

Override --rio-surface (cards, topbar, sidebar, table body).

pub fn text(self, color: impl Into<String>) -> Self

Override --rio-text (body text colour).

pub fn text_muted(self, color: impl Into<String>) -> Self

Override --rio-text-muted (secondary text, breadcrumb links).

pub fn border(self, color: impl Into<String>) -> Self

Override --rio-border (default divider, card outline).

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() -> AdminTheme

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.
