Enum style::values::generics::color::GenericColor

#[repr(C)]
pub enum GenericColor<Percentage> {
    Absolute(AbsoluteColor),
    ColorFunction(Box<ColorFunction<Self>>),
    CurrentColor,
    ColorMix(Box<GenericColorMix<Self, Percentage>>),
}

This struct represents a combined color from a numeric color and the current foreground color (currentcolor keyword).

Variants

Absolute(AbsoluteColor)

The actual numeric color.

ColorFunction(Box<ColorFunction<Self>>)

A unresolvable color.

CurrentColor

The CurrentColor keyword.

ColorMix(Box<GenericColorMix<Self, Percentage>>)

The color-mix() function.

Implementations

impl GenericColor<Percentage>

pub const TRANSPARENT_BLACK: Self = _

A fully transparent color.

pub const BLACK: Self = _

An opaque black color.

pub const WHITE: Self = _

An opaque white color.

pub fn from_color_mix(color_mix: ColorMix) -> Self

Create a new computed Color from a given color-mix, simplifying it to an absolute color if possible.

pub fn resolve_to_absolute( &self, current_color: &AbsoluteColor, ) -> AbsoluteColor

Combine this complex color with the given foreground color into an absolute color.

impl<Percentage> Color<Percentage>

pub fn as_absolute(&self) -> Option<&AbsoluteColor>

If this color is absolute return it’s value, otherwise return None.

pub fn currentcolor() -> Self

Returns a color value representing currentcolor.

pub fn is_currentcolor(&self) -> bool

Whether it is a currentcolor value (no numeric color component).

pub fn is_absolute(&self) -> bool

Whether this color is an absolute color.

Trait Implementations

impl<Percentage: Clone> Clone for GenericColor<Percentage>

fn clone(&self) -> GenericColor<Percentage>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Percentage: Debug> Debug for GenericColor<Percentage>

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

Formats the value using the given formatter.

impl<Percentage> MallocSizeOf for GenericColor<Percentage>

where Percentage: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<Percentage: PartialEq> PartialEq for GenericColor<Percentage>

fn eq(&self, other: &GenericColor<Percentage>) -> 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<Percentage> ToAnimatedValue for GenericColor<Percentage>

where Percentage: ToAnimatedValue,

type AnimatedValue = GenericColor<<Percentage as ToAnimatedValue>::AnimatedValue>

The type of the animated value.

fn from_animated_value(from: Self::AnimatedValue) -> Self

Converts back an animated value into a computed value.

fn to_animated_value(self, context: &Context<'_>) -> Self::AnimatedValue

Converts this value to an animated value.

impl<Percentage> ToShmem for GenericColor<Percentage>

where Percentage: ToShmem,

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.
