Enum ColorScheme 

pub enum ColorScheme {
    Default,
    ForceLight,
    ForceDark,
    PreferLight,
    PreferDark,
}

App-side intent for color-scheme resolution; mirrors libadwaita’s AdwColorScheme.

Resolution rules (see StyleManager):

• ColorScheme::ForceLight -> always light, ignore system.
• ColorScheme::ForceDark -> always dark, ignore system.
• ColorScheme::PreferLight -> follow system; default light when unknown.
• ColorScheme::PreferDark -> follow system; default dark when unknown.
• ColorScheme::Default -> follow system; default light when unknown.

Variants

Default

Follow the OS-reported preference; fall back to light when no preference has been detected yet.

ForceLight

Force light regardless of OS preference.

ForceDark

Force dark regardless of OS preference.

PreferLight

Prefer light but follow OS overrides when reported.

PreferDark

Prefer dark but follow OS overrides when reported.

Implementations

impl ColorScheme

pub fn from_name(s: &str) -> Option<Self>

Parse the Rhai / FFI / @media flavoured names: "default", "auto", "force-light", "force-dark", "prefer-light", "prefer-dark", "light", "dark". Case-insensitive. Returns None on unknown.

Trait Implementations

impl Clone for ColorScheme

fn clone(&self) -> ColorScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorScheme

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

Formats the value using the given formatter.

impl Default for ColorScheme

fn default() -> ColorScheme

Returns the “default value” for a type.

impl From<bool> for ColorScheme

fn from(is_dark: bool) -> Self

Legacy bridge: true -> ColorScheme::ForceDark, false -> ColorScheme::ForceLight. Mirrors the pre-W4.6 OsTheme.is_dark bool, but lets old code lean on Into<ColorScheme> without a bespoke convert_* helper.

impl Hash for ColorScheme

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 ColorScheme

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

impl Copy for ColorScheme

impl Eq for ColorScheme

impl StructuralPartialEq for ColorScheme
