Struct style::values::computed::color::Color

pub struct Color {
    pub color: RGBA,
    pub foreground_ratio: u8,
}

This struct represents a combined color from a numeric color and the current foreground color (currentcolor keyword). Conceptually, the formula is "color * (1 - p) + currentcolor * p" where p is foreground_ratio.

Fields

color: RGBA

RGBA color.

foreground_ratio: u8

The ratio of currentcolor in complex color.

Methods

impl Color

pub fn rgba(rgba: RGBA) -> Color

Returns a numeric color representing the given RGBA value.

pub fn transparent() -> Color

Returns a complex color value representing transparent.

pub fn currentcolor() -> Color

Returns a complex color value representing currentcolor.

pub fn is_numeric(&self) -> bool

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

pub fn is_currentcolor(&self) -> bool

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

pub fn to_rgba(&self, fg_color: RGBA) -> RGBA

Combine this complex color with the given foreground color into a numeric RGBA color. It currently uses linear blending.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Color

impl Debug for Color

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl MallocSizeOf for Color

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 ToAnimatedValue for Color

type AnimatedValue = AnimatedColor

The type of the animated value.

fn to_animated_value(self) -> Self::AnimatedValue

Converts this value to an animated value.

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

Converts back an animated value into a computed value.
