Struct style::values::animated::color::RGBA

pub struct RGBA {
    pub red: f32,
    pub green: f32,
    pub blue: f32,
    pub alpha: f32,
}

An animated RGBA color.

Unlike in computed values, each component value may exceed the range [0.0, 1.0].

Fields

red: f32

The red component.

green: f32

The green component.

blue: f32

The blue component.

alpha: f32

The alpha component.

Methods

impl RGBA

pub fn transparent() -> Self

Returns a transparent color.

pub fn new(red: f32, green: f32, blue: f32, alpha: f32) -> Self

Returns a new color.

Trait Implementations

impl MallocSizeOf for RGBA

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 Clone for RGBA

fn clone(&self) -> RGBA

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for RGBA

impl Debug for RGBA

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

Formats the value using the given formatter.

impl PartialEq for RGBA

fn eq(&self, __arg_0: &RGBA) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &RGBA) -> bool

This method tests for !=.

impl ToAnimatedZero for RGBA

fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation's "by-animation" where SMIL first interpolates from the zero value to the 'by' value, and then adds the result to the underlying value.

impl Animate for RGBA

Unlike Animate for computed colors, we don't clamp any component values.

FIXME(nox): Why do computed colors even implement Animate?

fn animate(&self, other: &Self, procedure: Procedure) -> Result<Self, ()>

Animate a value towards another one, given an animation procedure.

impl ComputeSquaredDistance for RGBA

fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>

Computes the squared distance between two animatable values.
