Enum ColorOrSystem 

#[repr(C, u8)]
pub enum ColorOrSystem {
    Color(ColorU),
    System(SystemColorRef),
}

A color reference that can be either a concrete color or a system color. System colors are lazily evaluated at runtime based on the user’s system theme.

CSS syntax: system:accent, system:text, system:background, etc.

Variants

Color(ColorU)

A concrete RGBA color value.

System(SystemColorRef)

A reference to a system color, resolved at runtime.

Implementations

impl ColorOrSystem

pub const fn color(c: ColorU) -> Self

Create a new ColorOrSystem from a concrete color.

pub const fn system(s: SystemColorRef) -> Self

Create a new ColorOrSystem from a system color reference.

pub fn resolve(&self, system_colors: &SystemColors, fallback: ColorU) -> ColorU

Resolve the color against a SystemColors struct. Returns the system color if available, or falls back to the provided default.

pub fn to_color_u_with_fallback(&self, fallback: ColorU) -> ColorU

Returns the concrete color if available, or a default fallback for system colors. Use this when SystemColors is not available (e.g., during rendering setup).

pub fn to_color_u_default(&self) -> ColorU

Returns the concrete color if available, or a gray fallback for system colors.

Trait Implementations

impl Clone for ColorOrSystem

fn clone(&self) -> ColorOrSystem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorOrSystem

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

Formats the value using the given formatter.

impl Default for ColorOrSystem

fn default() -> Self

Returns the “default value” for a type.

impl From<ColorU> for ColorOrSystem

fn from(color: ColorU) -> Self

Converts to this type from the input type.

impl Hash for ColorOrSystem

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 Ord for ColorOrSystem

fn cmp(&self, other: &ColorOrSystem) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ColorOrSystem

fn eq(&self, other: &ColorOrSystem) -> 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 PartialOrd for ColorOrSystem

fn partial_cmp(&self, other: &ColorOrSystem) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
