Enum BuiltInTheme 

#[non_exhaustive]
pub enum BuiltInTheme {
    Slate,
    Charcoal,
    Frost,
    Paper,
}

One of the four built-in elegance themes, as a typed enum.

Useful as the bound value for ThemeSwitcher or anywhere you want to remember a theme choice without stringly-typing it. Marked #[non_exhaustive] so future built-in additions won’t break exhaustive matches in downstream code.

let choice = BuiltInTheme::Frost;
let theme = choice.theme();
assert_eq!(choice.label(), "Frost");
assert!(!theme.palette.is_dark);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Slate

Theme::slate — cool dark blue. The default.

Charcoal

Theme::charcoal — neutral dark grey.

Frost

Theme::frost — light counterpart to slate.

Paper

Theme::paper — light counterpart to charcoal.

Implementations

impl BuiltInTheme

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

Display label used by ThemeSwitcher.

pub fn theme(self) -> Theme

Resolve to a concrete Theme.

pub const fn all() -> [BuiltInTheme; 4]

All four built-in themes in their canonical display order: dark variants first (Slate, Charcoal), then light (Frost, Paper).

Trait Implementations

impl Clone for BuiltInTheme

fn clone(&self) -> BuiltInTheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuiltInTheme

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

Formats the value using the given formatter.

impl Default for BuiltInTheme

fn default() -> BuiltInTheme

Returns the “default value” for a type.

impl Hash for BuiltInTheme

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BuiltInTheme

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